Question

the area of rombhus is 45cm2 and one of the diagnols is 7.5cm . Find the other diagonal =------cm​

Answer 1

Answer:

12 cm

Step-by-step explanation:

area=1/2*D1*d2

..........

Answer 2

Solution :-

Given ,

• Area of rhombus = 45 cm²
• Diagonal 1 [ d1 ] = 7.5 cm

We need to find ,

• Other diagonal [ diagonal 2 ( d2 ) ] = ?

As we know that ,

• Area of rhombus = 1/2 × d1 × d2

Now , substituting the known values ,

→ 45 = 1/2 × 7.5 × d2

→ 45 = 3.75 × d2

→ 45 ÷ 3.75 = d2

→ d2 = 12 cm

Hence , the other diagonal ( d2 ) = 12 cm
