podryga [215]

Answer:

The length of the patio is 32 ft and the width is 13 ft

Step-by-step explanation:

see the attached figure to better understand the problem

Let

L ----> the length of his patio

W ---> the width of his patio

we know that

L+2W=58 ----> equation A

L=2W+6 ----> equation B

substitute equation B in equation A and solve for W

2W+6+2W=58

4W+6=58

4W=58-6

4W=52

W=13\ ft

Find the value of L

L=2W+6  ----> L=2(13)+6=32\ ft

therefore

The length of the patio is 32 ft and the width is 13 ft
