Question

DL and BM are the height on sides a b and D respectively from parallelogram ABCD if the area of parallelogram is 300 CM square a 20 to 30 cm and 8 is equal to 20 cm find the length of beam and 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

Given, Area = 1470 cm2, AB = 35cm and AD = 49 cm, then BM =?, DL = ?.

Considering AB = Base;

Area = Base x Height
