# DL and BM are the heights on sides AB and AD respectively of parallelogram ABCD (Fig 11.24). If the area of the parallelogram is 1470 cm^{2}, AB = 35 cm and AD = 49 cm, find the length of BM and DL.

**Solution:**

AB = 35 cm, AD = BC = 49 cm and Area = 1470 cm^{2}

Area of parallelogram ABCD = Base (AB) × Height (DL)

1470 cm^{2 }= 35 cm × DL

DL = 1470 cm^{2 }/ 35 cm

DL = 42 cm

Area of parallelogram ABCD = Base (AD) × Height (BM)

1470 cm^{2 }= 49 cm × BM

BM = 1470 cm^{2 }/ 49 cm

BM = 30 cm
