Question

Adjacent sides of a rectangle are 8cm and 15cm find the length of its diagonal​

Answer 1

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
