A rectangle is 4 times as long as it is wide. A second rectangle is 5 centimeters longer and 2 centimeters wider than the first. The area of the second rectangle is 270 square centimeters greater than the first. What are the dimensions of the original rectangle?
I don't quite understand the correct process to go through when doing this, so could you show me how you get the answer? Thanks again guys!
expand the brackets on the left. (take each term in the first set of brackets and multiply every term in the second set)Originally Posted by quartersworth
by the way, janvdl made a slight error here, a minor oversight, i make them all the time. the question said "The area of the second rectangle is 270 square centimeters greater than the first"
thus, the right side of the equation should be:
