Question 6:DL and BM are the heights on sides AB and AD respectively of parallelogram ABCD (Fig11.24). If the area of the parallelogram is 1470 cm?, AB = 35 cm and AD = 49 cm, find thelength of BM and DL.MAnswer 6:Fig 11.24

Answer»

BM=1470÷49=30cmDL=1470÷35=42cm

area of parallelogram=h×b DL×AB DL×351470÷35=42cm height so, height is also BMbut we find length of BM area of parallelogram=h×b1470÷49. 49×BM =30cm is length BM
