Question

One side of a rhombus is 20cm and one of the diagonal is 24 cm. find the area of the Rhombus

Answer 1

DRAW 2 DIAGONALS IN THE RHOMBUS

In one triangle, a2 + b2 = c2

a = 12  b =? c= 20

144 +b2 = 400

b2 = 400- 144

   = 256

b = 16

length of the second diagonal is 32

area of rhombus = 1/2 * d1 * d2

                            = 1/2 * 24*32

                            =384
