Question

The sides of a rectangle are 20m and 15m respectively. The lenght of its diagonal is

Answer 1

Answer:

25m

Step-by-step explanation:

Lets asume a right angle triangle with sides 20m and 15m and hypoteneuse x. Then,

20^2 + 15^2 = x^2

400 + 225 = x^2

625 = x^2

Sq root (625) = x^2

25 = x

Therefore, the lenght of the diagonal is 25m
