Question

DL and BM are the heights on sides AB and AD respectively of parallelogram ABCD. If the area of the parallelogram is 1470 CM square, AB = 35 cm and AD = 49 cm, find the length of bm and DL​

Answer 1



Given that, Area of the parallelogram = 1470 sq. cm.

But, area of the parallelogram = base × height

⇒ AB× DL = 1470

⇒ 12 × DL = 1470



 The length of DL = 122.5 cm

In the same way,

Given that, Area of the parallelogram = 1470 sq. cm.

But, area of the parallelogram = base × height

⇒ AD× BM = 1470

⇒ 49 × BM = 1470



 The length of BM = 30 cm

 

Question 2:

What will be the height of parallelogram if base=20cm and area = 246cm.

Solution:

Area of the parallelogram = 246 sq. cm.

But, area of the parallelogram = base × height

⇒  Base ×  height = 246

⇒ 20 × height = 246



 The height of the parallelogram = 12.3 cm
