Answer:
17cm
Step-by-step explanation:
We know that, adjacent sides of rectangle are perpendicular to each other
so, adjacent sides of rectangle and its diagonal make right angled triangle
let sides be S1 and S2
by Pythagoras theorem
(S1)²+(S2)²=(diagonal)²
8²+15²=(diagonal)²
64+225=(diagonal)²
289=(diagonal)²
so,diagonal = 17cm
