Question

1. classroom drawn 6 in × 4 in, scale 1 in = 3 ft. find actual dimensions.
2. path on drawing is 7 in long, scale 1 in = 2 ft. find actual length.

Explanation:

Step1: Calculate actual length for classroom

For the classroom, scale is \(1\) in \( = 3\) ft.
Length on drawing \(l_d=6\) in, actual length \(l_a = 6\times3=18\) ft.
Width on drawing \(w_d = 4\) in, actual width \(w_a=4\times3 = 12\) ft.

Step2: Calculate actual length for path

For the path, scale is \(1\) in \(=2\) ft.
Length on drawing \(L_d = 7\) in, actual length \(L_a=7\times2=14\) ft.

Answer:

• Classroom actual dimensions: \(18\) ft \(\times12\) ft
• Path actual length: \(14\) ft
