# 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
