Question

Two side of a parallelogram are 20cm and 25cm if the height corresponding to the sides of length 25cm is 10cm find the height corresponding to the other pair of side

Answer 1

let the height be x

area of para.

base × height =25×10=20×x

x=25×10÷20

x=12.5

Answer 2

are of parallelogram is 1/2×base×height
Therefore for 25cm side area=1/2×25×10=125cm^2

Now even for side 20cm area of parallelogram is 125cm
Therefore, area of parallelogram=1/2×20×height
125=10×height
height=12.5cm
