Question

THE AREA OF A RECTANGLE IS 192 SQ CM AND IT'S LENGTH IS 16 CM ∴ IT'S DIAGONAL = ?

Answer 1

Answer /-

We know that , area of a rectangle = Length × Width

Or , 192Cm ² = 16 × Width

Or , 192 / 16 = Width

Or , Width = 192 / 16

Or , Width = 12 Cm

Using pythagoras theorem /-

Digonal ² = Length ² + Width ²

Digonal ² = 16 ² + 12 ²

Digonal ² = 256 + 144

Digonal ² = 400

Digonal = √(400)

Digonal = 20 Cm

Hence , The Digonal of the rectangle is 20 Cm .
