Quantitative Aptitude ( CCS) Ratio, Proportion

The perimeter of a rectangle is 64 cm. If the ratio of the lengths of two adjacent sides is 7: 9, find the lengths of these sides.

24 cm, 28 cm

14 cm, 18 cm

7 cm, 9 cm

None of these

Perimeter of a rectangle = 2 (L + B)

Also L: B = 7 : 9

Actual values are 5x and 8x.

2(7x + 9x) = 64

. → x = 2

Sides will be of 14 cm and 18 cm.

Hence, opiton 2 is the correct answer.
