Question

The adjacent sides of a parallelogram
are in the ratio 5:3. If the length of the longer side is 7.5cm, find the perimeter of the parallelogram.​

Answer 1

Answer:

12cm

Step-by-step explanation:

adjacent sides of a parallelogram

are in the ratio 5:3

length  of longer side = 5x and smaller  side = 3x

given that ,

5x = 7.5cm

x = 7.5cm/5 = 1.5cm

so

3x = 3(1.5cm) = 4.5cm

perimeter = 2(1.5cm + 4.5cm) = 12cm
