Question

.DL and BM are the height on sides AB and AD
respectively of parallelogram ABCD. If the area of
parallelogram is 300 cm, AB = 30 cm and
AD = 20 cm. Find the length of BM and DL.
​

Answer 1

Answer:

DL=BM=15cm

Step-by-step explanation:

Area is parallelogram ABCD=base×height

300 =AD×DL

300 =20×DL

300/20=DL

15=DL

Therefore DL=15cm

opposite sides of parallelogram are congruent. Therefore there heights are also congruent.

Therefore DL=BM=15cm
