Question

An architect is designing a school courtyard that is 45 feet long and 30 feet wide. What will be the measurement of the drawing? Use a scale of 0.5inch = 10 feet. \\\

Answer 1

L= 2.25 in

W= 1.5 in

Explanation:

Step one:

given

The dimension of the courtyard is 45 feet long and 30 feet wide

Required

The measurement of the drawing given the scale 0.5inch = 10 feet.

Step two:

1. The length of the drawing

if 0.5 in represents 10 ft

then x in will be 45ft

cross multiply

45*0.5= 10x

22.5=10x

divide both side by 10

x= 22.5/10

x=2.25in

2. The width of the drawing

if 0.5 in represents 10 ft

then y in will be 30ft

cross multiply

30*0.5= 10y

15=10y

divide both side by 10

y= 15/10

y=1.5in
