प्रश्न

DL and BM are the heights on sides AB and AD respectively of parallelogram ABCD (see the given figure). If the area of the parallelogram is 1470 cm2, AB = 35 cm and AD = 49 cm, find the length of BM and DL.

बेरीज

उत्तर

Area of parallelogram = Base × Height

= AB × DL

1470 = 35 × DL

DL = `1470/35`

DL = 42 cm

Also, area of parallelogram = AD × BM

1470 = 49 × BM

∴ BM = `1470/49`

∴ BM = 30 cm
