Question

the side of a rectangle are 22 cm and 120 CM respectively find the length of its diagonal​

Answer 1

Answer:

Step-by-step explanation:

find the squares of both 22 and 120 then add them. Find the square root of the result and the answer you get is the diagonal.

Answer 2

Answer:

The diagonal of the rectangle measures 122 cm.

Step-by-step explanation:

Let the measure of diagonal be x.

By observing the diagram, we can get that we can apply Pythagoras formula here. i.e. a² + b² = c²

As we know, the line which is

exactly in front of the right angle equals to the other two sides.

So,

According to the question,

(a² + b² = c²)

⇒ 22² + 120² = c²

⇒ (22*22) + 120* 120) =c²

⇒ 484 + 14400 = c²

⇒ √14884 = c

⇒ 122 = c

So, the measure of diagonal is 122 cm.
