Question

The diagonals of a rhombus are in the ratio 2:3 if their sum is 15 cm find the area of rhombus .

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Step-by-step explanation:

let the diagonals of rhombus be 2× and 3×

this is given that the sum of the diagonal is 15cm

so,

2× + 3× = 15

5× = 15

× = 15

Hence,

the diagonal of rhombus =2×=6cm

=3×=9cm

Now,

the area of the rhombus = 1/2×(a×b)

=1/2×(6×9)

=27cm²

the area of the rhombus = 27cm²
