Do you solve this?

Calculate the area S of a rectangle and the lengths of its sides if its perimeter is 472 cm and the sides are in the ratio of 1:3.

Final Answer:

S =  10443 cm2
a =  59 cm
b =  177 cm

Step-by-step explanation:

o=472 cm a:b=1:3 b=3a  o=2(a+b) = 2(a+3a) = 2 4a = 8a  a=o/8=472/8=59 cm b=3 a=3 59=177 cm  S=a b=59 177=10443=10443 cm2   Verifying Solution:   o2=2 (a+b)=2 (59+177)=472 cm r=a:b=59:177=310.3333=1:3
