please Mark me brainlest I need to level up pls

Answer 2

Given,

Length of the room = 48 m

Breadth of the room = 14m

Since it's a rectangle , all angles will be 90°

and according Pythagorean Theorem ,

(side 1)^2 + (side 2)^2 = (hypotenuse)^2

48^2 + 14^2 = (hypotenuse)^2

2304 + 196 = (hypotenuse)^2

2500 = (hypotenuse)^2

√2500 = hypotenuse

50 m = hypotenuse

here hypotenuse is only the diagonal .

So diagonal is 50m
