Find the area of the triangle.
21 in.
12 in.

A =126 in ^2

Step-by-step explanation:

The area of a triangle is given by

A = 1/2 bh where b is the base and h is the height

A = 1/2 ( 12) 21

A =126 in ^2

The area of triangle is 126 inches ².

Step-by-step explanation:

Base of triangle = 12 inches

Height of triangle = 21 inches

Area of triangle

Area of triangle = 1/2 × base × height

Using Formula

Area of triangle = 1/2 × base × height

substitute the values into the formula

Area of triangle = 1/2 × 12 inches × 21 inches.

multiply,

Area of triangle = 1/2 × 252 inches ²

Divide, we get

Area of triangle = 126 inches ²

Therefore, The area of triangle is 126 inches ².
