Question

the perimeter of a rectangle is 13 cm and its width is 2 3/4 cm . find its length

Answer 1

Answer:

Let the length be l

Given width is w=2(3/4) = 11/4 cm

Then by perimeter formula we have

13=2(i+w)

=> l+11/4=13/2

=>l=13/2-11/4

=> l=15/4 cm

=>l=3(3/4) cm in mixed fraction form

Answer 2

Answer:

PERIMETER OF RECTANGLE: 13CM

WIDTH IS 2(3/4)

LENGTH=?

P=2[L+B]

=>P=2L+11/2

=>13-11/2=2L

=>L=15/4.
