Answer :
one thing that may help is the use of diagrams. See the attached photo.
To solve you need two equations.
2w + 2L = 22
L = w + 3
2w + 2(w + 3) = 22
2w + 2w + 6 = 22
4w + 6 = 22
4w = 16
w = 4
L = w + 3
L = 4 + 3
L = 7
The width of the rectangle is 4 inches.
What is perimeter of rectangle?
The formula for the perimeter of a rectangle is, P = length + breadth + length + breadth.= 2(length+ breadth)
Given: perimeter= 22 inches.
Let the width be 'b'
length= b+3
Perimeter of rectangle= 2(l+b)
22 = 2(b+3+b)
11= 2b+3
11-3=2b
8=2b
b=4 inches
So, length= b+3= 7 inches
Hence, the width of rectangle is 4 inches.
