You can put this solution on YOUR website! With this question, break down the sentence into bits and pieces.
"The width of a rectangle is..."
w =
"1 foot shorter than half the length."
l - 1
"If the perimeter of the rectangle is 64 feet..."
P = 64
(NOTE: Remember P = 2l + 2w)
"Find the dimensions of the rectangle."
Find "l" and "w."
Now that we have those, we piece it all together.
w = l - 1
P = 2l + 2w
64 = 2l + 2( l - 1)
Use the distributive property.
64 = 2l + l - 2
Combine like terms, and add two to both sides.
66 = 3l
Divide both sides by 3.
22 = l
Now that we have "l," we can find "w" by plugging it into w = l - 1.
* 22 - 1
