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

Answer:

Step-by-step 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.

$A=\frac{1}{2}bh$ and filling in:

$54=\frac{1}{2}b(12)$ 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
