Question

The blueprint for the pelham's living room has a width of 12 inches using the scale of 2 inches = 7 feet.

The family wants to use a scale of 1 inch = 6 feet. What is the width of the living room on the new blueprint?

Answer 1

The new blueprint's width will be 7 inches.

Explaination:

• Find the width of the actual room

Create a proportion: 2in:7ft

Divide 12 by 2 and multiply by 7 to find the real width: 6•7=42

• Find new width

Divide actual width by 6 and multiply by 1 to find the new scale: (42/6) •1 = 7
