Find the area of the shaded area.
25 !

56cm²

Step-by-step explanation:

Step 1:  Find the area of the whole square, including the non-shaded region

It's a square, so A= LW      (Area is the product of the legth and width)

A = (8)(8) = 64 cm²

Step 2:  Find the area of the non-shaded region

It's a triangle so A = (1/2)bh    

It's also a right triangle, so the height is also the side length

A = (1/2)(4)(4) = 8 cm²

Step 3:  Subtract the area of the non shaded region from the shaded region

A = 64 cm² - 8 cm² = 56 cm²
