In a square the sum of the length of three sides is 48 and in a rectangle the same as a side of the square how is long is a length of the rectangle?

In a square, the sum of the lengths of three sides is 48 and in a rectangle

the difference between a length and a width is 7 in.

If a width of the rectangle is the same as a side of the square, how long is a length of the rectangle?

:

Let s = side of the square and the width of the rectangle

:

"In a square, the sum of the lengths of three sides is 48"

3s = 48

s = 48/3

s = 16

:

" in a rectangle the difference between a length and a width is 7 in."

L = s + 7

L = 16 + 7

L = 23 is the length of the rectangle

Answer: 23

Step-by-step explanation: The length of one side of the square must be 48 / 3 = 16

And in the rectangle we have that

L - W = 7

So

L - 16 = 7 add 16 to both sides

L = 23
