The perimeter of a rectangle is 60cm. The length (L) of the rectangle can be represented by (2x-7). What are the dimensions?

A) length=10 width=14
B) length=6 width=18
C) length=9 width=15
D) length=10 width=1 or 15

I'm stumped. l+w = 30

and none of the choices fits that.

your choices for answers have perimerters of (twice length+twice width) of

a. 20+28=48
b. 12+36=48
c. 18+30
d. 20+30

none are sixty. No answer is correct.

bobpursely can u help me with a question?

To find the dimensions of the rectangle with the given perimeter, we need to set up an equation using the formula for the perimeter of a rectangle.

The formula for the perimeter of a rectangle is: P = 2L + 2W, where P is the perimeter, L is the length, and W is the width.

In this case, the perimeter is given as 60cm, so we have:
60 = 2L + 2W

The length of the rectangle is given as (2x - 7). Let's substitute it into the equation:
60 = 2(2x - 7) + 2W

Simplifying the equation, we get:
60 = 4x - 14 + 2W

Now, we need to find the value of the width. To do this, we need additional information or another equation relating the length and width. Without this information, we cannot determine the exact dimensions of the rectangle.

Therefore, the given information is not sufficient to find the dimensions of the rectangle.
