Question

ratio of two adjacent sides of a parallelogram is 2:3 and its perimeter is 120 cm. find the length of its each side.​

Answer 1

$let \: the \: two \: sides \: be \: 2x \: and \: 3x \: \\ perimeter = 120cm \\in \: parallelogram \: the \\ \: opposite \: sides \: are \: congruent \: \\ 2x + 2x + 3x + 3x = 120 \\ 10x = 120 \\ x = \frac{120}{10} \\ x = 12 \\ so \\ 2x = 24cm \\ 3x = 36cm$

Therefore, sides are 24cm,36cm,24cm and 36cm.
