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 diagram: triangle with height 3 in, base 2.5 in, scale 1 in. : 4 ft

Explanation:

Step1: Find actual base

The scale is 1 in. : 4 ft. The base on the diagram is 2.5 in. To find the actual base, multiply the diagram base by the scale factor.
Actual base = \(2.5 \times 4\)
\(2.5\times4 = 10\) ft

Step2: Find actual height

The height on the diagram is 3 in. Multiply the diagram height by the scale factor (4 ft per inch) to get the actual height.
Actual height = \(3\times4\)
\(3\times4 = 12\) ft

Answer:

Actual base = 10 ft
Actual height = 12 ft
