Question

The perimeter of a rectangle is 13 cm and its width is 11 / 4 .then what is the length

Answer 1

Step-by-step explanation:

perimeter = 2*(length+width)

13 = 2*(length+11/4)

13/2 = length + 11/4

length = 13/2 - 11/4 = 26-11/4 = 15/4

Answer 2

Answer:

Length of the rectangle is 15/4cm.

Step-by-step explanation:

Given, perimeter of rectangle = 13cm

breadth (B) = 11/4cm

length (L)= ?

so, perimeter of rectangle = 2(L+B)

13 = 2(L + 11/4)

13 = 2(4L+11)/4

2×13 = 4L + 11

4L = 26 - 11

4L = 15

L = 15/4 cm

Hence, Length of the rectangle is 15/4cm.
