Table

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 result:

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

Solution:


2(a+b)=420
2a=5b

2•(a+b)=420
2•a=5•b

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



We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you!
