Question

Help me plz, explain it

Answer 1

The perimeter of a rectangle is found by multiplying the length by 2 and the width by 2 and adding them together.

P = 2L + 2W

Filling in the information given we can find the width:

16.8 = 2(3.6) + 2W

16.8 = 7.2 + 2W

2w = 16.8 - 7.2

2w = 9.6

w = 9.6 / 2

w = 4.8 in.

Answer 2

A rectangle has 2 equal lengths and 2 equal widths. If one length is 3.6 then multiply by 2 = 7.2
So then 16.8 - 7.2 = 9.6
Then divide 9.6 by 2 = 4.8
