Question

A rectangular playground has a width of 540

feet and a length of 810 feet. Martina makes a
scale model of the playground using a scale of
1 cm:7.5 ft.
What are the dimensions of Martina's scale
model?

Answer 1

Answer: 72cm by 108cm

Explanation:

basically, take your numbers so, 4 / 30 in a fraction form, then take a random letter, i'm using n and put n / 540 (this also will be the same for 810!)

n x 30 = 30n, 4 x 540 = 2160, divide that by 30 (which is 72) then do the SAME process but with 810 (which then you get 108) and BAM you got your answer. good luck!
