salantis [7]

Answer:

The length of other wall is 3 meters.

Step-by-step explanation:

Given that:

Length of one wall = 4 meters

Length of diagonal from one corner to opposite corner = 5 meters

As the room is rectangular, the diagonal will form a right angled triangle.

The diagonal will be the hypotenuse.

Using pythagorean theorem;

$a^2+b^2=c^2$

Here,

a = 4 and c = 5

$(4)^2+b^2=(5)^2\\16+b^2=25\\b^2=25-16\\b^2=9$

Taking square root on both sides

$\sqrt{b^2}=\sqrt{9}$

b = 3 meters

Hence,

The length of other wall is 3 meters.
