Question

Area of the Rhombus is 21sq.cm. If one of its diagonal is 7cm then the another diagonal is​

Answer 1

Solution!!

The area and one diagonal of a rhombus is given in the question. We have to find the other diagonal.

Area = 21 cm²

Diagonal = 7 cm

Let the other diagonal be x.

We know that,

Area = Product of the diagonals ÷ 2

21 = (7 × x) ÷ 2

21 × 2 = 7x

42 = 7x

x = 42 ÷ 7

x = 6 cm

Hence, the other diagonal of the rhombus is 6 cm.
