Question

Find the length of a rectangle given that the perimeter is 110 cm and the length is lcm more than twice the width. Do not

include units in your answer.

Answer 1

width = w = 18cm

length = 2w+1 =2(18)+1 =36+1 =37cm

Explanation:

width = w

length = 2w+1

perimeter = 2(length +width)

110 =2(2w+1+w)

110 = 2(3w+1)

110 = 6w+2

108 =6w

18 = w

width = w = 18cm

length = 2w+1 =2(18)+1 =36+1 =37cm
