Question

The length of the diagonal of the rectangular floor of a room is 2.25m and that of one of its sides is 1.44 m. Find the area of the floor.

Answer 1

Answer:

2.49 m^2 (approx.)

Step-by-step explanation:

Given,

Diagonal length = 2.25 m

one side = 1.44 m

To find : Area of the floor.

Soln.

Since, it is a rectangular floor, we know that,

Diagonal^2 = Length^2 + Breadth^2 ... [Pythagoras principal for right  

                                                                   angles]

Applying the values,

2.25^2 = 1.44^2 + Breadth^2

Breadth^2 = 2.25^2 - 1.44^2 = 5.0625 - 2.0736 = 2.9889

Breadth = sq.root(2.9889) = 1.73 m (approx.)

Now,

Area of rectangular floor = Length * Breadth = 1.44 * 1.73 = 2.49 m^2 (approx.)

Answer 2

Answer:

2.49 m^2
