Answer»

Step-by-step explanation:

Question:-

The DIAGONAL of a rhombus are 7.5cm and 12CM. Find its area.

Answer:-

Given :-

• The given figure is a rhombus.

• The length of its TWO diagonal are 7.5cm and 12cm.

To find :-

Area of the rhombus

Process :-

As we all KNOW that:-

⇒Area  \: of \: rhombus =  \frac{pq}{2}  \:  \:  \: (p  \: and  \: q  \: are \:  the \:  two  \: diagonals  \: of \:  rhombus) \\  \\

Inserting the above value in the formula:-

⇒Area =  \frac{pq}{2}  \\  \\ ⇒Area =  \frac{7.5×12}{2}  \\  \\ ⇒Area =  \frac{90}{2}  \\  \\ ⇒Area = 45cm²

Therefore,we can conclude that the area of the rhombus is 45cm².
