Question

the perimeter of a parallelogram is 60 cm and the ratio of width at the sides is 3 ratio 2 if the altitude corresponding to larger side of the parallelogram is 5 cm find the area of parallelogram and the altitude corresponding to the smaller side​

Answer 1

2(3x + 2x) = 60

3x + 2x = 30

5x = 30

x = 6

larger side 3x = 18

smaller side 2x = 12

area = larger side × h

= 18 × 5

= 90 sq cm

area = smaller side × h

90 = 12 × h

h = 90/12

h = 7.5 cm
