Question

what number can you multiply each length in the scale drawing by to find the actual length? 3 what are the actual length and width of the trampoline? actual length = ft actual width =? ft l = 4 in. w = 2 in. 1 in. : 3 ft

Explanation:

Step1: Identify the scale factor

The scale is 1 in. : 3 ft, so the number to multiply by is 3.

Step2: Calculate actual length

Given scale - drawing length $l = 4$ in. Multiply by scale factor. $4\times3=12$ ft.

Step3: Calculate actual width

Given scale - drawing width $w = 2$ in. Multiply by scale factor. $2\times3 = 6$ ft.

Answer:

Actual length = 12 ft
Actual width = 6 ft
