Question

The diagonal of a rectangle whose length is 15cm and breadth is 8cm​

Answer 1

diagonal is 17 cm

Explanation:

use pathagorean theorem

you have a = 8, b= 15

c is the diagonal of the rectangle (rectangle has 90deg angles)

c^2 = a^2 + b^2

c^2 = 8^2 + 15^2

c^2 = 64 + 225

c^2 = 289

take square root

c = 17
