QUESTION: 2

The length of the diagonal of the square is 10 cm. The area of the square is:

Solution:

If side of square is 'a', then √2a = 10 Squaring both sides, 2a^{2 }=100 a^{2 }= 50 Area is 50 sqcm.

QUESTION: 3

The diagonal of a square is 10 cm. Its area is:

Solution:

Let x = the length of a side of the square

So area of square = x^{2} = 50cm^{2}

QUESTION: 4

QUESTION: 5

The diagonals of rhombus are 12 cm and 16 cm. The length of the side of rhombus is:

Solution:

We know that, the diagonals of a rhombus are perpendicular bisector of each other.

Given, AC = 16 cm and BD = 12 cm [let]

∴ AO = 8cm, SO = 6cm

and ∠AOB = 90°

In right angled ∠AOB,
