Question

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: Determine the conversion factor

The scale is 1 in. : 2 ft, which means 1 inch in the drawing represents 2 feet in actual.

Step2: Calculate the actual base

The base in the drawing is 4 in. Using the scale, we multiply by 2. So the actual base $b = 4\times2=8$ ft.

Step3: Calculate the actual height

The height in the drawing is 5 in. Using the scale, we multiply by 2. So the actual height $h = 5\times2 = 10$ ft.

Answer:

Actual base = 8 ft
Actual height = 10 ft
