I'm stumped. l+w = 30
and none of the choices fits that.
A) length=10 width=14
B) length=6 width=18
C) length=9 width=15
D) length=10 width=1 or 15
and none of the choices fits that.
a. 20+28=48
b. 12+36=48
c. 18+30
d. 20+30
none are sixty. No answer is correct.
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.
