Two similar FOR SALE signs have a scale factor of 5:3. The largest sign’s perimeter is 60 inches. Find the small sign’s perimeter.

Answers

Answer 1
Answer:

The perimeter of small sign is: 36 inches

Step-by-step explanation:

The ratios will be used to solve the question

Given

Ratio of larger to smaller sign = 5:3

Perimeter larger sign = 60 inches

If there is a scale factor between the signs, there will be a scale factor between perimeters of both signs

Let x be the perimeter of smaller sign

So,

5:3 = 60:x\n(5)/(3) = (60)/(x)\n5x = 180

Dividing both sides by 5

(5x)/(5) = (180)/(5)\nx = 36

The perimeter of small sign is: 36 inches
