Answer:
56 cm²
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 length 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
