Question 633787: define a variable, write an equatiom, and solve the problem. The width of a rectangle is 3 meters more than one-fourth its length. The perimeter is 10 meters more than twice its length. find the length and width Answer by solver91311(24713) (Show Source):
If the perimeter is 10 more than twice the length, then 10 must be twice the width (refer to the formula for the perimeter of a rectangle), hence the width has to be 5.
If the width, which we now know to be 5 is 3 more than 1/4 of the length, 1/4 of the length has to be 2, hence the length is 4 times 2 or 8.
