The length of a rectangle is 3 times the width. If the length is increased by 4 cm and the width is decreased by 1 cm,the parimeter would be 102 cm, find the dimensions of the original rectangle.
2 answers
the permeter of a rectangle is 90cm what is the area of the rectangle if the width is (2x+6) and the length is (3x-1)
2((3w+4)+(w-1)) = 102
w=12
2((2x+6)+(3x-1))) = 90
x=8
So, on both problems, you can now figure the answers needed.
