7.5cm and 12cm. Its area is
O
(a)40 square cm
O
(b)45 square cm
0 (0)55 square cm
0 (d)65 square cm​

Answer 1

Answer:

(b)45 cm

Step-by-step explanation:

i m writing the explanation but if it is only objective than you can tick 45 cm ^2

Let d1 and d2 be the two diagonals of a rhombus.

Then, d1=7.5 cm and d2=12 cm

We know that,

Area of Rhombus=d1d2/2 =(7.5)(12)/2

=45 cm^2

Hence, the answer is 45cm2.

I hope it helps

mark me brailiest please

note :the formula of area of rhombus used here is d1d2/2

and if your teacher gave you the formula 1/2 d1d2

then dont get confused both are correct

Answer 2

Answer:

b) 45cm²

Explanation :

Area of a rhombus is given by :

→ ½ • $d_1$ • $d_2$

Where,

• $d_1$ = 7.5cm
• $d_2$ = 12cm

So, the area of the rhombus is :

→ ½ • 7.5 • 12

→ 7.5 • 6

→ 45.0

Area of the rhombus is 45cm²

Note behind :

The $d_1$ and $d_2$ are the diagonals of the rhombus. [Follow the attachment ]
