Question

Alicia is making a triangular sign for the school play. The area of the sign is 558 in. The base of the triangle is 36in. What is the height of the triangle?

Answer 1

Answer:31 in

Step-by-step explanation:558 ×1/2 ×36 × h = 31 in

Answer 2

To find the height of the triangle you will use the formula to find the area of the triangle and the information provided about the area and the base length.

A= 1/2 bh
558 = 1/2 x 36 x h
558 = 18 x h

To solve for the height divide both sides by 18.

This leaves you with 31 = h.

So, the height is 31 inches.
