the perimeter of a retangle room is 166 feet. find the length and width of the room if the length is 5 feet longer than twice the width

anonymous · Answer

You have to remember the formula for perimeter of a rectangle to figure this out

anonymous · Answer

let the width W = w ft
then length L = (w + 5) ft

Perimeter of rectangle = 2L + 2W

ATQ,
166 = 2(w + 5) + 2(w)
166 = 2w + 10 + 2w
166 - 10 = 4w
156/4 = w
39 = w

so width = 39 ft
length = (39 + 5) = 44 ft
