Question

What is the formula of diagonal of rectangle?

Answer 1

d = √(l^2 + b^2)
where l = length
w = width
We say it as diagonal of a rectangle is equal to length square plus breadth/width square.

Answer 2

Rectangle : A rectangle is a plane figure which have four right angles and pair of opposite sides are equal.

Now,

Area of rectangle = length × breadth (unit)²

Perimeter = 2 ( length × breadth )

Diagonal of rectangle = √ ω² + ℓ²

Here, we have

L = length

W = B = breadth
