Question

If a triangle has a height of 12 inches and a base of 5 inches, what's its area? A. 30 sq. in. B. 60 sq. in. C. 45 sq. in. D. 90 sq. in.

Answer 1

A = (hb) / 2
A = (12 * 5) / 2 = 60/2 = 30 sq in

Answer 2

option A is correct.

Area of a triangle is 30 square inches.

Explanation:

Area of triangle is equal to multiply the base by the height, and then divide by 2.

i.,e
`A = (1)/(2)bh`

where

A is the area of triangle

b is the base of the triangle

h is the height of the triangle.

As per the given statement:

height(h) = 12 inches and base(b) = 5 inches.

Substitute these given values to get area of the triangle;

`A = (1)/(2)bh`

`A = (1)/(2)(5)(12) = 5 * 6 = 30` square inches.

therefore, the area of a triangle is 30 square inches
