Question

2 The Skoblickis are building a new home. The scale

Answer 1

The actual width of the room is 20 ft and the actual length of the room is 15 ft

Since on the scale, 2 in : 5 ft and the width of the room on the drawing is 8 in.

Let the actual width of the room is w.

The ratio of the drawing to actual width is   8 in : w

So, 2 in : 5 ft = 8 in : w

2 in/5 ft = 8 in/w

So, w = 8 in × 5 ft/2 in

w = 4 × 5 ft

w = 20 ft

Also, the length of the room on the drawing on the drawing is 6 in.

Let the actual length of the room is L.

The ratio of the drawing to actual length is   6 in : L

So, 2 in : 5 ft = 6 in : L

2 in/5 ft = 6 in/L

So, L = 6 in × 5 ft/2 in

L = 3 × 5 ft

L = 15 ft

So, the actual width of the room is 20 ft and the actual length of the room is 15 ft.
