Question

The perimeter of a rectangle is 38 inches,if the length is 3 inches more than the width ,find the width

Answer 1

Answer:

The width is 8 inches.

Step-by-step explanation:

2l + 2w = 38

l = w + 3

2(w + 3) + 2w = 38

2w + 6 + 2w = 38

4w + 6 = 38

4w = 32

w = 8

l = 11

11 + 11 + 8 + 8 = 38

Answer 2

Answer:

8 inches

Step-by-step explanation:

We are given:  2L+2W=38  or simplified version: L+W=19

                          L=3+W

So plug 2nd equation into first, like so, (3+W)+W=19

                                                                 3+W+W=19

                                                                 3+2W=19

                                                                     2W=16

                                                                       W=8
