Question

The length of rectangle A is 7.4 cm and the width is 4.8 cm. The perimeter of rectangle B is 14.9 cm. How much is the perimeter of rectangle A than the perimeter of rectangle B?

Answer 1

Answer: 9.5 cm

Explanation:

First we have to find the perimeter of rectangle A:

Formula for perimeter of a rectangle or square is:
`2(a+b)`

Putting the length and width in:
`2(7.4+4.8)`

Solve it to get: 24.4 cm

Subtract 14.9 from 24.4 to get 9.5 cm
