Question

In square abvd ac is 16cm then area of abcd is __cm square

Answer 1

Answer:

128 cm²

Step-by-step explanation:

Since we have ABCD as square.

Therefore we have AC as diagonal 16cm

Explanation:

Now we can apply the formula

Area of a square = (diagonal) ²/ 2

So, by using this formula we will find the area.

(AC) ² / 2

(16)² / 2

256 / 2

=128 cm²

Answer 2

Answer:

Given: ABCD is a square with a diagonal AC of 16 cm.

Step-by-step explanation: Diagonal of a square=√2 x side

16= √2 x a(Let the side be 'a')

a= 16/√2 cm

Area of square= side²

= (16/√2)²

= 256/ 2

= 128 cm²
