Question

need some math help please asap
Gino designed a garden for his rectangular backyard. The design he drew on paper is ten inches long. The length of his backyard is forty feet. If his drawing is to scale, and his backyard is twenty-eight feet wide, how many inches wide is his drawing? Write a proportion using words. Then, use the proportion to calculate the drawing width. Show your work.

Answer 1

10 inches = 40 feet
divide both sides by 10
1 inch = 4 feet
28 feet / 4 feet = 7
so it's 7 inches

Answer 2

since the drawing can be scaled and the ratio of a feature from drawing:garden is coonstant, we can write,
constant scale ratio=10/40=1/4=drawing length/actual length
similarly writing drawing width/actual width=1/4 and so we get drawing width=7
