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 rectang
le.
1 answer:
Answer:
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
