Cut this into 3 figures
OpenStudy (dtan5457):
2 squares, one rectangle.
OpenStudy (dtan5457):
Both squares (left and right of the figure) are 20 by 20
OpenStudy (dtan5457):
20 times 20=400
2 squares=800, now just find the rectangle's area

Hello, do you know how to find the area of a rectangle ?
You could find the area of the big triangle 20*60 then subtract the area of the small rectangle from it 10*20.
OpenStudy (dtan5457):
The rectangle has a height of 10, when you subtract the 20-10 from the square.
TOTAL LENGTH:60
2 square take 40 of that, therefore the rectangle's length is 20.
20 times 10=200, add that to the area of the 2 squares
OpenStudy (dtan5457):
and you get your answer which is ________?
OpenStudy (math&ing001):
aka Area = 20*60 - 10*20
