Question

A game room has a floor that is 200 feet by 40 feet. A scale drawing of the floor on grid paper uses a scale of 2 units:5 feet. What are the dimensions of the scale drawing

Answer 1

200 FEET

2 units/5 feet = x units/200 feet

x = 2/5 (200) = 400/5 = 80 units

Cross Multiplication

5x = 2(200)

x = 400/5 = 80 units

Explanation:

Answer 2

200 FEET
2 units/5 feet = x units/200 feet
x = 2/5 (200) = 400/5 = 80 units

Cross Multiplication
5x = 2(200)
x = 400/5 = 80 units

40 FEET
2 units/5 feet = x units/40 feet
x = 2/5(40) = 80/5 = 16

Cross Multiply
2/5 = x/40
5x=80
x = 80/5 = 16

Dimensions of Scale Drawing:
80units × 16units
