Question

A rectangle has a long side of length 8.5 cm.

Its perimeter is 24 cm.

Work out the length of the shorter sides.

Answer 1

Answer:

hope you understand. this, I think, is the right answer.

Answer 2

The length of the shorter side is 3.5 cm.

length = 8.5 cm

perimeter = 24 cm

perimeter of a rectangle = 2(l + w)

Therefore,

24 = 2(8.5 + w)

24 = 17 + 2w

subtract 17 from both sides

24 - 17 = 2w

7 = 2w

w = 7 / 2

w = 3.5 cm

Therefore, the length of the shorter side is 3.5 cm
