Respuesta :

length=3width-5

(2(x))+(2(3x-5)=46

2x+6x+10=46

8x=56

x=7

width=7 length=16

Answer:

w = 7

l = 3w-5

2l + 2w = 46

lets substitute the value of length

2(3w-5)+2w

6w-10+2w

6w+2w = 8w

8w-10 = 46

add 10 to both sides to cancel out the -10 on the left side.

8w = 56

56/8 = 7

w = 7
