Question

The perimeter of a rectangle is 34 units. It's width is 6.5 units write an equation to determine the length (l) of the rectangle. Find the length of the rectangle

Answer 1

Perimeter = 2 * length + 2 * width
2 * length = perimeter - 2 * width
length = (perimeter / 2) - width

length = (34 / 2) -6.5
length = 10.5
