Two squares

Two squares whose sides are in the ratio 5:2 have sum of its perimeters 73 cm. Calculate the sum of area this two squares.

Correct result:

S1+S2 =  197.1 cm2

Solution:

a1a2=52=o1o2 73=o1+o2=4(a1+a2)  a1=5734(5+2)=13.0357 cm a2=2734(5+2)=5.2143 cm S1=a12=169.93 cm2 S2=a22=27.19 cm2 S=S1+S2197.1 cm2
