The original square was 6 ft along each side.
Let s be the side of the original square, then:
Area_square = s x s = s2
Area_new_square = (s + 4) x (s + 4) = s2 + 8s + 16
But:
Area_new_square = Area_square + 64
=> s2 + 8s + 16 = s2 + 64
=> 8s = 48
=> s = 6

How do you find the original price when you know the percent of increase?
Okay. If you have the percent increace, you cannot find the original price. BUT if you have the percent increace and the INCREACED PRICE than you take 100 and minus the percent increace and then divide adapted price by that number. than times THAT by 100. (EX. 75% INCREACE AND ENDING PRICE 15$) ( THAN 100-75=25 SO 15X25=375 THAN 375DIVIDEDBY100=3.75 3.75 ORIGINAL.

A rectangle has a base of 5 inches and a height of 7 inches If the dimensions are cut in half what will happen to the area of the rectangle?
It doesn't make any difference what the original dimensions are. If they're both cut in half, the area is reduced to 1/4 of the original area.
How can you determine the scale factor of a dilation by looking at a segment and its image?
Every part of the original scales by the same scale factor. By using a segment of the original you will determine the scale factor by dividing the length of the image by the length of the original.
When each side of a given square is increased by 3 feet the area is increased by 39 square feet Determine the dimensions of the original square?
Designate the side length of the original square by s. Then, from the problem statement, (s + 3)2 = 39 + s2. Multiplying out the binomial and collecting like terms yields 6s = 30 or s = 5.
