Rectangle - sides 4

The perimeter of the rectangle is 72 cm. Calculate the length of the sides that are in the ratio of 3:5.

Final Answer:

a =  13.5 cm
b =  22.5 cm

Step-by-step explanation:

o=72 cm o=(2a+2b) = 2 (a+b) = 2 (3+5) = 2 8=16d  d=o/16=72/16=29=4.5  a=3 d=3 4.5=13.5 cm
b=5 d=5 4.5=245=22.5=22.5 cm   Verifying Solution:   o2=2 (a+b)=2 (13.5+22.5)=72 cm
