Question

The diagonals of a rhombus are 7 cm and 10 cm, then find out the area of this rhombus.

(a) 20 sq. cm
(b) 17.5 sq. cm
(c) 70 sq. cm
(d) 35 sq. cm​

Answer 1

Answer:

area of rhombus is 1/2×product of its diagonals

Step-by-step explanation:

1/2×7×10

1/2×70

2 will cut 70 by 35

1×35

35cm²

therefore 35 is the correct answer

Answer 2

Step-by-step explanation:

$\huge{\underline{\mathtt{\red{ƛ}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}} :) :)$

Let d1 and d2 be the two diagonals of a rhombus

Then, d 1 =7 cm and d2 =10 cm

We know that,

$\tt{ \frac{(d1) \times (d2)}{2} } \\ \tt{ = \frac{7 \times 10}{2} } \\ \frac{70}{2} \\ \huge\tt \blue{= 35sq.cm}$
