Question

15. A room should have a rectangular floor,
with sides of lengths 7 m and 24 m. A builder wants to check that the room is a perfect rectangle (that is all the angles
are right angles). He measures the two diagonals of the room, what should be thelength of the diagonals, which would verify that the room is a rectangle.​

Answer 1

Answer:

25

Step-by-step explanation:

let, breadth be $b$

     length be $l$

or, diagonal should be $\sqrt{l^2+b^2}=\sqrt{7^2+24^2}=\sqrt{625}=25$

because if the room is a rectangle then the diagonal should be the hypotenuse of the triangle
