Question

Calculate the perimeter of a rectangle that is 5.5 c by 3.5 cm?

Answer 1

the answer should be 18 cm

you can either do 2 × (length + width)

2 × (5.5 + 3.5)

2 × 9 = 18

or

5.5 + 5.5 = 11

3.5 + 3.5 = 7

11 + 7 = 18

either way it's 18, I hope this helps

Answer 2

P = 2 x (5,5 + 3,5) = 18 cm

P = is the circumference of the figure
