The circumference of the rectangle table is 420 cm. Length to width ratio is 5:2 . Calculate table dimensions and dimensions reduced in the ratio 3:5

Correct answer:

a =  150 cm
b =  60 cm
c =  90 cm
d =  36 cm

Step-by-step explanation:



2a+2b = 420
2a-5b = 0

a = 150
b = 60

Our linear equations calculator calculates it.
k=3/5=35=0.6 c=k a=0.6 150=90 cm
d=k b=0.6 60=36 cm
