Question

Thhe diagonals of a rhombus are in ratio 3:4 if the longer diagonal is 12cm then find the are of rhombus​

Answer 1

Answer:

Rhombus area = 1/2 x diagonal a x diagonal b

Ratio = 3:4

longer diagonal = 12 cm

means that the ratio 4 = 12 cm

we have to find ratio 3

we have to put the value to find ratio 3

1/2 x diagonal a x 12

diagonal a x 12 = Area

diagonal a x 12 = 1/2 x a x 12

diagonal a x 12 = a x 6

diagonal a x 12/6 = a

a will be cut

a = 2 cm
