4. What is the area of rectangle FGHK?

A=32.2490

Step-by-step explanation:

First, use Pythagorean theorem to find the missing side to be able to find the area.

A^2+B^2=C^2

4^2+B^2=(4.5+4.5)^2

16+B^2=81

B^2=81-16

B^2=65

B=square root of 65

B=8.06

Now you can plug into the A=B*H

A=4*8.06

A=32.2490
