HELP PLS I BEG U

A rectangle has a length of 3.6 in. and a perimeter of 16.8 in.



Enter the width of the rectangle, in decimal form, in the box.

Answer 1

Perimeter = 2l + 2w

l = 3.6

w = unknown

3.6 + 3.6 = 7.2

16.8 = 7.2 + 2w

16.8 - 7.2 = 9.6

9.6 = 2w

4.8 = w

The width is 4.8.

Answer 2

width = 4.8 in

Explanation:

Perimeter = 16.8 in

2 * ( length + width ) = 16.8

2 * ( 3.6 + width ) = 16.8

3.6 + width = 16.8/2

3.6 + width = 8.4

width = 8.4 - 3.6 = 4.8 in
