The perimeter of five squares are 24 cm, 32 cm, 40 cm, 76cm and 80 cm respectively. The perimeter of another square equal in area to sum of the areas of these squares is :

Explanation:

side of the square =perimeter\4

∴ Sides of all five squares are

=24\4,32\4,40\4,76\4,80\4

=6,8,10,19,20

ATQ

Area of another square

=6^2+8^2+10^2+19^2+20^2

(side)^2=36+64+100+361+400

side=√961=31

Perimeter of new dquare =4×side

=4×31=124
