Question

jazlyn wants to purchase a triangular trampoline. ( a = \frac{1}{2}bh ). what are the actual base and height of the trampoline? actual base = (square) ft. actual height = ? ft. 1 in. : 4 ft. (image of a triangle with base 2.5 in, height 3 in)

Explanation:

Step1: Find actual base

The scale is 1 in. : 4 ft. The base on the diagram is 2.5 in. So actual base = 2.5 * 4.
$2.5\times4 = 10$

Step2: Find actual height

The height on the diagram is 3 in. Using the scale, actual height = 3 * 4.
$3\times4 = 12$

Answer:

Actual base = 10 ft
Actual height = 12 ft
