Best ResponseYou've already chosen the best response.0what is the area of this parallelogram

karatechopper

Best ResponseYou've already chosen the best response.1I think its just B x H

andrea408

Best ResponseYou've already chosen the best response.0so 6 + 4 ? 10 and times 20 ?

karatechopper

Best ResponseYou've already chosen the best response.1Ok..you see how there this a small triangle in the parallelogram?

karatechopper
 3 years ago
Best ResponseYou've already chosen the best response.1Ok. That A stands for Area. And that A is in the triangle. So its saying that the area of the triangle is 20. So we need to find the height of the triangle before trying to find the are of the paralellogram.

karatechopper

Best ResponseYou've already chosen the best response.1So..whats the base of the triangle?

karatechopper
 3 years ago
Best ResponseYou've already chosen the best response.1Good. Now do you have any idea of how to find the height of the triangle?

andrea408
 3 years ago
Best ResponseYou've already chosen the best response.0no i dont, how do you find it ?

karatechopper
 3 years ago
Best ResponseYou've already chosen the best response.1Ok..well one way is that you can put the info you have in the area of a triangle formula and solve fore the height..it would look like this.. (4 x H)1/2=20 SOLVE IT! The 4 is for the Base..the 20 is for the area..

andrea408

Best ResponseYou've already chosen the best response.0oh i was right the first time then

karatechopper

Best ResponseYou've already chosen the best response.1Yeh! Now that you know what the height is, you can now find the area of the parallelogram

karatechopper

Best ResponseYou've already chosen the best response.1Its going to be the basic formula B x H

Best ResponseYou've already chosen the best response.0The area of a triangle is (1/2) its base length times its corresponding height. If the base is 4.5 and the height 4, then the Area is (1/2)*(4.5)*4 Area = ?

andrea408

Best ResponseYou've already chosen the best response.0the area would be 810 ?

Directrix

Best ResponseYou've already chosen the best response.0Then, please check the diagram. The base is marked 4.5 and the height 4. That would be 9 square miles. Check to see if the diagram is marked correctly. @andrea408

Best ResponseYou've already chosen the best response.0whats the area of this trapazoid ?

Directrix

Best ResponseYou've already chosen the best response.0The area of a rectangle is the product of the length and the width. The area of a triangle is (1/2)b * h. So, ... dw:1360024949464:dw

Directrix

Best ResponseYou've already chosen the best response.0Area of trapezoid is (1/2) * 6 * 14 + 13 * 14 A = ?

Directrix

Best ResponseYou've already chosen the best response.0Try again > (1/2) * 6 * 14 + 13 * 14  Do onehalf of the product of 6 and 14. Add that answer to the product of 13 and 14 and post what you get.

andrea408

Best ResponseYou've already chosen the best response.0so the area of the trapazoid is 224 ?

Best ResponseYou've already chosen the best response.0What are the options?

andrea408

Best ResponseYou've already chosen the best response.0i dont have options . i just put in the answer and click done to see if its correct but im scared to click

Best ResponseYou've already chosen the best response.0If the picture is correctly drawn and labeled, I am certain that the answer is 224 square feet.

jim_thompson5910

Best ResponseYou've already chosen the best response.0the base is 4.5, the height is 3 so the area is just base * height = 4.5 * 3 = 13.5 square miles

jim_thompson5910

Best ResponseYou've already chosen the best response.0In general Area of Parallelogram: A = B*H B = base H = height

andrea408

Best ResponseYou've already chosen the best response.0so the area of ABDF is just 13.5 ?
