Question

What is the area of the shaded region? IXL assignment

Answer 1

100 ft²

Explanation:

The area of the shaded region is the area of the outer triangle minus the area of the inner triangle.

For a triangle,

A = bh/2

A = 13 × 20/2 + 10 × 6/2

A = 130 - 30

A = 100

Answer: 100 ft²

Answer 2

Answer: 100

Explanation:

20*13 = 260

260/2 = 130

10*6 = 60

60/2 = 30

130-30 = 100
