As sides of rectangle are perpendicular to each other so △ABC is a right angle triangle.

If the sides of a rectangular plot are 15 m and 8 m, then the length of its diagonal is? Pythagoras Theorem, ML Aggarwal Understanding Mathematics Solutions ICSE Class 9.

In right angle triangle ABC,

⇒ AC2 = AB2 + BC2

⇒ AC2 = 82 + 152

⇒ AC2 = 64 + 225

⇒ AC2 = 289

⇒ AC = 289\sqrt{289} = 17 m.

Hence, Option 1 is the correct option.
