Question

In the parallelogram ABCD ,AE and AF are heights corresponding to the sides BC and CD respectively . If the area of the parallelogram is 1200 sq cm and AE and AF are respectively 40cm and 60 cm , find the length of the sides of the parallelogram.​

Answer 1

Answer:

Given: Area of parallelogram=1470 cm2

Base(AB)=35 cm and base(AD)=49 cm

Since, Area of parallelogram=base×height

⇒1470=35×DL

⇒ DL=351470

⇒ DL=42 cm

Again, Area of parallelogram=base×height

⇒1470=49×BM

⇒BM=491470

⇒BM=30 cm

Thus, the lengths of DL and BM are 42 cm and 30 cm respectively.
