Question

The area of a triangle is one-half times the base times the height. If the area of a

triangle is 54 sq. in, and its height is 12 in., what is the base?

Answer 1

Explanation:

You already know the formula for area of a triangle, so we will write it down and then fill it in with the info given.

`A=(1)/(2)bh` and filling in:

`54=(1)/(2)b(12)` and we can simplify that a bit by dividing 12 by 2 on the right side to get:

54 = 6b and dividing:

b = 9 inches
