Solution

Let ABCD be the ||gm in which BC = 30 cm

and CD = 20 cm

Distance between shorter sides,

i.e. CQ = 15 cm

∴ area of ||gm = AB × CQ

= 20 × 15

= 300 cm2

Again BC × AP = Area of || gm

30 × AP = 300

AP = `300/30`

AP = 10 cm

∴ Distance between larger sides is = 10 cm

  Is there an error in this question or solution?
