Problema Solution
a rectangle is 54 cm. the length is 2 cm more than a "x" and the width is 5 cm less than twice the "x". Solve for "x". Round your answer to the nearest whole number.
Answer provided by our tutors
We assume the perimeter of the rectangle is 54 cm:
P = 54 cm
Length = 2 + x
Width = 2x - 5
Since the formula for the perimeter is:
P = 2*Length + 2*Width
We plug the given value into the above formula:
2(2 + x) + 2(2x - 5) = 54
