One side of a rectangle is 45% of the length of its other side. What are the dimensions of a rectangle if its perimeter is 101.5 cm?

Correct answer:

a =  35 cm
b =  15.75 cm

Step-by-step explanation:

r=45%=10045=209=0.45 o=101.5 cm  b=r a o  = 2a+2b o = 2a+2 r a  a=2+2 ro=2+2 0.45101.5=35 cm
b=r a=0.45 35=463=15.75=15.75 cm   Verifying Solution:  o2=2 (a+b)=2 (35+15.75)=2203=101.5 cm
