no
jim_thompson5910

tell me what the area of the rectangle is
anonymous
  • anonymous
its an 8 by 2 rectangle
jim_thompson5910
  • jim_thompson5910
what is the area
jim_thompson5910
  • jim_thompson5910
area of rectangle = length times width
anonymous
  • anonymous
how do i find the area of the rectangle
jim_thompson5910
  • jim_thompson5910
multiply the length and width
jim_thompson5910
  • jim_thompson5910
as the formula suggests
anonymous
  • anonymous
is the length and width 8 x 2
jim_thompson5910
  • jim_thompson5910
8 is the length 2 is the width multiply them
anonymous

2 square units
jim_thompson5910
  • jim_thompson5910
no you use the formula A = h*(b1+b2)/2 h = 10 b1 = 4 b2 = 1

@jim_thompson5910
jim_thompson5910
  • jim_thompson5910
have a look at this article http://www.mathgoodies.com/lessons/vol1/area_trapezoid.html
anonymous
  • anonymous
ok i did
jim_thompson5910
  • jim_thompson5910
use the ideas used in the article to find the area of that trapezoid I highlighted
jim_thompson5910
  • jim_thompson5910
add the parallel bases divide by 2 then multiply by the height
anonymous
  • anonymous
i got 25
jim_thompson5910
  • jim_thompson5910
area of rectangle = 16 area of trapezoid = 25 add up the two areas to get 16+25 = 41 41 is the area of the shaded region |dw:1433982064961:dw|
jim_thompson5910
  • jim_thompson5910
(Area of nonshaded region) = (Area of the largest rectangle) - (Area of shaded region)
anonymous
  • anonymous
ok so know lets find the answer for the non shaded region @jim_thompson5910
jim_thompson5910
  • jim_thompson5910
what is the Area of the largest rectangle?
anonymous
  • anonymous
is it 8 x 2
