Question

DL and BM are the heights on sides AB and AD redpectively of parallelogram ABCD if the area of the parallelogram is 1470sq² AB=35cm and AD=49cm,find the length of BMand DL​

Answer 1

Answer:

Considering AB = Base;

Area = Base x Height

⇒ 1470 cm2 = AB x DL

⇒ 1470 cm2 = 35cm x DL

Or, DL = 1470 ÷ 35 = 42 cm

Now considering AD = Base;

Area = Base x Height

⇒ 1470 cm2 = AD x BM

⇒ 1470 cm2 = 49 cm x BM

Or, BM = 1470 ÷ 49 = 30 cm

Hence, DL = 42 cm and BM = 30 cm
