Question

Please send an explanation :)

Answer 1

Answer:

100 cm^2

Step-by-step explanation:

if FA and BF are the same and the shape is a square then  the right triangles

FBC and FEC have the same area. FA is 1/2 the length of the square.

if you rotate FEC to the bottom of the square the shaded are will be 1/2 of the square. 50 = 1/2 of the square... unshaded left square = 50 , and 50 = unshaded on the right

total unshaded should be 100 cm^2
