What is the area of the unshaded region of the rectangle? part 1. Show work please

96 m²

Step-by-step explanation:

The unshaded region is a right triangle.

The area (A) of the triangle is calculated as

A = bh ( b is the base and h the perpendicular height )

Calculate b using Pythagoras' identity in the right triangle

b² + 16² = 20²

b² + 256 = 400 ( subtract 256 from both sides )

b² = 144 ( take the square root of both sides )

b = = 12

Thus area of unshaded region is

A = × 12 × 16 = 6 × 16 = 96 m²

Step-by-step explanation:

You can easily solve this using Pythagorean Triplets:
