Question

The side of rectangle are 20m 15m respectively the length of diagonal is

Answer 1

Answer :

Given, the sides of the rectangle are 20 m and 15 m respectively.

Therefore, the length of the diagonal

= √(20² + 15²) m

= √(400 + 225) m

= √625 m

= √(25 × 25) m

= 25 m

Answer 2

Answer:

25 meters.

Step-by-step explanation:

Given:- Length of the rectangle = 20 meters.

            Breadth of the rectangle = 15 meters.

To Find:- Length of the diagonal whose sides are given.

Solution:-

Rectangle is a geometrical figure with four sides whose opposite sides are equal. Both the diagonals are equal and divides the rectangle into equal triangle.

Given length and breadth of rectangle is 20 meters and 15 meters.

(Diagonal)² = (length)² + (breadth)²    [ Pythagoras Theorem ]

⇒ (Diagonal)² = (20)² + (15)²

⇒ (Diagonal)² = 400 + 225

⇒ (Diagonal)² = 625

⇒ Diagonal = √625

⇒ Diagonal = 25 meters.

Therefore, length of the diagonal is 25 meters.
