Question

The perimeter of a rectangle 13cm and it
wilth is 23/4 cm.find it
s length?​

Answer 1

Answer:

we know perimeter = 2 x (l +b)

given ,

perimeter =13 cm

width/breadth =23/4 cm

now just put the given things in the formula

perimeter = 2 x ( length + breadth)

=> 13 = 2 x ( l + 23/4)

=> 13/2 = l + 23/4

=> 13/2 - 23/4 = l ( take lcm)

=> 26 - 23/4 = l

=> 3/4 = l

therefore the length is 23/4
