P = 2l + 2w
l = 2w
48 = 2(2w) + 2w
48 = 4w + 2w
48 = 6w
8 = w
l = 2w
l = 2(8)
l = 16
48 = 2(16) + 2(8)
48 = 32 + 16
48 = 48
Answer:
length = 16
width = 8
Step-by-step explanation:
Perimeter of a rectangle = 2l + 2w
where
l is the length
w is the width
From the question
The length is 3x + 7
The width is 2x + 2
The perimeter is
<h3>2( 3x + 7) + 2( 2x + 2)</h3>
Simplify
6x + 7 + 4x + 4
Group like terms
6x + 4x + 7 + 4
We have the final answer as
<h3>10x + 11</h3>
