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

Answer:

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
