Question

the length of a rectangle is 12cm and each diagonal measures 15cm.find its breadth

Answer 1

diagonal =✓length²+breadth²

Answer 2

Solution :-

Given :

Length of the rectangle = 12 cm

Length of each of its diagonal = 15 cm

⇒ Diagonal = √(Length)² + (Breadth)²

⇒ 15 = √(12)² + (Breadth)²

Squaring both the sides, we get.

⇒ 15² = 12² + Breadth²

⇒ 225 - 144 = Breadth²

⇒ Breadth² = 81

⇒ Breadth = √81

⇒ Breadth = 9 cm
