Question

The sides of a quadrilateral can be represented by the ratio 1 / (2 / (3/6)) . The perimeter is 138 cm . What is the length of the longest side ?

Answer 1

Answer:

Given rato =1:2:3:6

$1x + 2x + 3x + 6x = 138cm \\ 12x = 138cm \\ x = 138 \div 12 \\ x = 11.5 \\ longest \: side = 6x \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 6 \times 11.5 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 69$
