Question

DL and BM are the heights of sides AB and DC in parallelogram ABCD respectively .if the area of parallelogram ABCD is 1470 CM square a b is equal to 35 cm find the length of BM and DL

Answer 1

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
