Question

Find the area of each figure.

1. A triangle with base 6 in. and height 3 in. has an area of ____ inches squared.

2. A square with sides of 7.6 m has an area of ______ meters squared.

3. A triangle with base 8.2 cm and height 5.1 cm has an area of ____centimeters squared.

Answer 1

1. 9

2. 57.76

3. 20.91

Explanation:

1. area of a triangle = 1/2 x base x height

⇒ area = 1/2 x 6 x 3 = 9 in²

2. area of a square = side x side

⇒ area = 7.6 x 7.6 = 57.76 m²

3. area of a triangle = 1/2 x base x height

⇒ area = 1/2 x 8.2 x 5.1 = 20.91 cm²
