Question

The area of rhombus is 300cm square. The length of one of the diagonal is 20cm. The length of the other diagonal is​

Answer 1

Area of rhombus of diagonals d1 and d2

= 1/2 x d1 x d2 = 300 cm²

= 1/2 x 20 x d2 = 300 cm²

= 10 x d2 = 300 cm²

d2 = 300 ÷ 10 = 30 cm

∴ 30 cm is the length of the other diagonal.

Answer 2

Answer:

d2  = 580 cm.

Step-by-step explanation:

Area of Rhombus = d1*d2÷2

                  300     = 20 * d2 ÷  2 (∵d1 = 20 cm )

             300 * 2    = 20 * d2

              600        =   20*d2

            600 ÷20   = d2

            d2 = 30cm

∴ length of another diagonal is 30 cm.
