Question

A square and a rectangle have the same perimeter what is the side length of this square?

Answer 1

Answer:

Step-by-step explanation:

first step

find the perimeter of square which is 4s

side given of the square=16

so16*4=64

as the perimeter of square and rectangle are same

so the perimeter of rectangle is 64

64=2(l+b)

64/2=l+18

32=l+18

l=32-18

l=14

so the length of the rectangle is 14

Answer 2

Step-by-step explanation:

the question is not very clear.....any way with given information it can be like this....

Perimeter of square of side , say 'a' , will be:

P=4a

Perimeter of rectangle of length , say, 'l' and breadth , say 'b' will be:

P'=2(l+b)

Given that, P=P'

So, 4a=2(l+b)

So , side length of square,

a=(l+b)/2
