Question

The mean of perimeter of two squares having sides x units and y units?

Answer 1

Perimeter of first square = 4x
Perimeter of second square = 4y

Mean = (4x+4y) /2
= 2x + 2y

Answer 2

Perimeter of first square=4(side)=4x
Perimeter of second square=4(side)=4y
Mean of perimeters of two squares=(4x+4y)/2
=4(x+y)/2
=2(x+y)
