Question

4. Find the area of rhombus whose diagonals are:
(i) 12 cm, 21 cm​

Answer 1

Answer:

126cm2

Step-by-step explanation:

since the area of rhombus is calculated by 1/2 (product of its diagonals)

therefore 1/2 ×12×21 ( do the cancellation of 12 by 2..u'll get 6×21

=126cm2

hope it helps

Answer 2

HELLO!!

Area of rhombus:

$\frac{d1 \times d2}{2}$

┗(•ˇ_ˇ•)―→( d is daigonal)

so, if we substitute the values in its respective places we get,

$\frac{12cm \times 21cm}{2 } = \frac{ {252cm}^{2} }{2} = {126cm}^{2}$

final answer is 126 cm square
