Given:
Perimeter of a rectangle = 64 inches
Length = 22 inches
Determine the width.
Formula for the perimeter of a rectangle.
P = 2(l + w)
Solution:
Substitute the given values of perimeter and length to the formula for the perimeter of the rectangle, then we solve for w.
P = 2(l + w)
64 = 2 (22 + w)
64 =44 + 2w
Transpose 44 on the other side of the equation, note that when transposing a number, the sign changes.
64 -44 = 2w
20 = 2w
Divide both sides by 2 in order to get the value of w.
w = 10
Final answer:
The width of the rectangle is 10 inches
