Question

What’s the area of this figure?

Answer 1

470 square mm. the area of the right triangle is 128 sq mm because 32x11=256 and 256/2=128

Answer 2

374 mm

Explanation:

There are two rectangles and one triangle. This means that we need to add the sum of two rectangles and one triangle together.

Rectangle 1:

19*9=171

Rectangle 2:

19*9=171

Triangle:

8*23*1/2=32

(We divide by 1/2 because it's a triangle)

Now we add them together.

171+171+32=374

In the end, the answer is 374. I didn't show all of my work because most of it was done mentally.
