It's two triangles. You can solve for one triangle and multiply it by 2. and you will have the answer.

because 4 is a side length and square root of 48 is a side length multiply them together and you have the area its 27.7 which rounded is 28 inches, so A

first find the length
\(8^2-4^2=64-16=√48\)
\(4√48= 27.7~so ~28 \) would be the nearest square inch
OpenStudy (sissyedgar):
