Best ResponseYou've already chosen the best response.0the image wont show its a little trapezoid that is24m and a bigger trapezoid that is 57 mdw:1434053254505:dw

Best ResponseYou've already chosen the best response.0ok so the ratio of the corresponding side in is 57/24 you need to square this number and then multiply by the small area

Best ResponseYou've already chosen the best response.0if you know the ratio of the linear measurements, the ratio of the areas is the square of the linear ratio.. ratio of the volumes is the cube of the linear ratio

Best ResponseYou've already chosen the best response.0so the calculation is \[(\frac{57}{24})^2 \times 558\]

Best ResponseYou've already chosen the best response.0i don't understand its a trapezoid and they give me the area of the small on and i have to find the area of the big one and the small trapezoid has 24m under its biggest side and the big trapezoid as 57m under so i don't know how to get the big area oh the world is so much clearer now thank you

Best ResponseYou've already chosen the best response.0ok... they is a thing about similar shapes... all sides are in the same ratio... in your 2 trapezoids, the small has 24 in the same position as the 57 in the large. does that make sense...?

Best ResponseYou've already chosen the best response.0ok... here is the key, you don't need to find any side lengths in the larger trapezoid. just use the scaling factor... the scaling factor: large = 57 small = 24 so the scaling factor from small to large is \[\frac{57}{24} ~~or~~\frac{19}{8}\] does that make sense..?

Best ResponseYou've already chosen the best response.0next step is to square the scaling factor so calculate \[(\frac{19}{8})^2 = ?\] then multiply that value by the small area 558

Best ResponseYou've already chosen the best response.0that will give the area of the large trapezoid

Best ResponseYou've already chosen the best response.0here is an online calculator http://web2.0calc.com/ enter \[( 57 \div 24) ^2 \times 558 = \]

Best ResponseYou've already chosen the best response.0oh i kept multiply by 2!! thankyou i had to multiply by 5.64x558
