Question

The length of a rectangle is 6 more than twice its width. The

perimeter is 36 inches. Find the width of the rectangle.
A. 4
B. 5
C. 6
D. 10

Answer 1

The answer is option (C). The width of the rectangle=6 inches

Explanation:

Step 1: Determine the dimensions of the rectangle

width=w

length=w+6

Step 2: Determine the perimeter of the rectangle

P=2(L+W)

where;

P=perimeter

L=length

W=width

In our case;

P=36 inches

L=w+6

w=w

replacing;

2(w+w+6)=36

2(2 w+6)=36

4 w+12=36

4 w=36-12=24

4 w=24

w=24/4=6

W=6 inches

L=6+6=12 inches

The width of the rectangle=6 inches
