Question

Find the area of the triangle at the right. Round to the nearest tenth as needed.

Answer 1

A ≈ 62.3 ft²

Explanation:

the area (A) of the triangle is calculated as

A =
`(1)/(2)` product of 2 sides × angle between them , that is

A = 0.5 × 18 × 11.5 × sin37°

= 103.5 × sin37°

≈ 62.3 ft² ( to the nearest tenth )
