Question

the are of kite is 100 cubic cm and one of diagonal is 10 cm find another diagonal​

Answer 1

Answer :

The length of other diagonal of kite is 20 cm.

Step-by-step explanation :

Let us assume,

• The long diagonal of kite = d1
• The short diagonal of kite = d2

To Find,

• The length of other diagonal ( d1 ) of kite

Solution,

Given that,

• Area of kite = 100cm³
• Lenght of the diagonal ( d2 ) = 10cm

Therefore,

As we know that,

Area of kite = 1/2 × d1 × d2

➮ 1/2 × d1 × 10 = 100

➮ 1 × d1 × 5 = 100

➮ d1 × 5 = 100

➮ d1 = 100 / 5

➮ d1 = 20 ★

Hence, the other diagonal of the kite is 20cm.

Now, Verification

➮ 1/2 × d1 × 10 = 100

➮ 1 × 20 × 5 = 100

➮ 20 × 5 = 100

➮ 100 = 100

L.H.S = R.H.S

Hence, Verified !
