Question

An architect creates a scale model of a building with a scale of 3 inches =11 feet of the actual width of the building is 121 feet what is the width of the scale model

Answer 1

The width of the scale model is 33 inches.

Explanation:

This question is solved making a relation with the scale model.

In the scale, 3 inches are worth 11 real feet.

The actual width of the building is 121 feet, so we find it's scale by a rule of three.

3 inches - 11 feet

x inches - 121 feet

`11x = 121*3`

Simplifying by 3, both sides

`x = 11*3 = 33`

The width of the scale model is 33 inches.
