The length of adjacent two sides are 15 cm. and 12 cm. of a parallelogram distance between two smaller sides is 7.5 cm. Then let us calculate the distance between the longer two sides.

Given, The length of adjacent two sides are 15 cm. and 12 cm. of a parallelogram and distance between two smaller sides is 7.5 cm.

According to question, area of the parallelogram


= smaller side (base) × distance between smaller sides


= 12 × 7.5


= 90 sq. cm


Area of the parallelogram = longer side (base) × distance between longer sides


⟹ 90 = 15 × h


⟹ h =


⟹ h = 6cm
