Question

What is the area of the shaded region?

Answer 1

shaded area = 372.115 m²

Explanation:

the shaded area is calculated as

area of outer Δ - area if inner Δ

area of outer =
`(1)/(2)` bh ( b is the base and h the height )

=
`(1)/(2)` × 35.4 × 32.3

= 17.7 × 32.3

= 571.71 m²

area of inner =
`(1)/(2)` × 20.9 × 19.1

= 10.45 × 19.1

= 199.595 m²

then

shaded area = 571.71 - 199.595 = 372.115 m²
