​

Answer 1

Step-by-step explanation:

Let the diagonal be x

(X)2=(112)2+(15)2

Solve this

Answer 2

Answer:

113 cm.

Step-by-step explanation:

One diagonal of a rectangle produces two right-angled triangles with the diagonal as the hypotenuse and the angles opposite to the diagonal are 90°.

In one triangle having base = 15 cm. and perpendicular = 112 cm.

Hence, the length of the diagonal (the hypotenuse)= √(15²+112²) {Applying Pythagoras Theorem)

=√(12769)

= 113 cm.

Therefore the length of the diagonal is 113 cm. (Answer)
