Question

jazlyn wants to purchase the triangular trampoline shown. the scale is shown in the drawing. area of triangle = $\frac{1}{2}bh$. what are the actual base and height of the trampoline? actual base = ft. actual height = ft. 1 in. : 2 ft

Explanation:

Step1: Calculate actual base

Use scale factor. Given 1 in. : 2 ft, base is 4 in. So actual base = 4×2.
$4\times2 = 8$

Step2: Calculate actual height

Use scale factor. Height is 5 in. So actual height = 5×2.
$5\times2 = 10$

Answer:

Actual base = 8 ft
Actual height = 10 ft
