geometry problem

Area = 7*9 + pi*(5^2/2) + 7*4 = 91 + 25/2*pi

the idea is spliting your figure to 2 rectangles and 1/2 circle.

What is the area of this figure?

Hello Guest!

$A=9\times 3\ dm^2+(9+7)\times 4\ dm^2+(9+7-4-2)^2\times\frac{3.14}{4\cdot 2}\ dm^2$

$A=130.25 \ dm^2$

A = 7 * 9 + 7 * 4 + ( 5² * 3.14 ) / 2 = 130.25 cm²

Why have you all done this person's homework.

Wouldn't they have more chance of learning something if you just gave hints?
