​

Answer 1

Answer:

perimeter=2(l+b)

p= 42

b=8

l=x

2(l+8)=42

2l+16=42

2l= 26

l=13 inches

Answer 2

Step-by-step explanation:

The perimeter of a rectangle is 42 inches. If the width of the rectangle is 6 inches,what is the length?

Remember that the Perimeter of a rectangle is the distance around it.

So,

Perimeter = Length + Width + Length + Width

or

P = 2L + 2W

If P=42 inches and W = 6 inches,

42 = 2L + 2(6)

42 = 2L + 12

30 = 2L [subtract 12 from both sides]

15 = L [divide both sides by 2]

The length (L) is 15 inches.
