The perimeter of a rectangle is 13 cm and its width is 11/4 cm .find its length ???



!!!​

Answer 1

perimeter = 13cm

breadth = 11/4 cm

length = ?

perimeter = 2(l+b)

13 = 2( l+11/4)

13/2 = l + 11/4

l = 13/2 - 11/4

length = 15/4 cm

Answer 2

Perimeter =2(l+b)

13= 2(l+11/4)

13 = 2l + 11/2

13-11/2=2l

15/2 = 2l

15/4=length
