The perimeter of a rectangle is 78 inches. The width is "w" and the length is 2x+3. Find the width and the length of the rectangle.

width = 12 Inches

length = 27 Inches

Step-by-step explanation:

Perimeter of Rectangle Formula is 2 (l+w), Therefore,

2 (l+w) = 78 inches (Equation 1)

l = 2x+3 (Equation 2)

Let width be x

Putting width as x and l as 2x+3 in equation 1

2 (2x+3+x) = 78

2 (3x+3) = 78

6x+6=78

6x=72

x=12

Putting width=>x = 12 inches in equation 2 to find the length

l=2 (12) + 3

l=27 inches
