The length of a rectangle is represented by 3x + 4, and its width is represented by 2x + 1. The

perimeter of the rectangle is 25 units. Find the value of x.

Answer: X=1.5

Step-by-step explanation:

Solution

Perimeter = 2 (l+w)

25 = 2 (3x+4 + 2x+1)

25 = 2 (3x+2x+4+1)

25 = 2 (5x+5)

25 = 10x+10

Now subtract 10 on both sides ...

25-10 = 10x+10-10

15=10x

Now divide 10 on both sides to get x

15/10 = 10x/10

1.5=X
