Question

5. Find the length of the diagonal of a rectangle whose sides are 15 cm and 8 cm.
​

Answer 1

Answer:

17

Step-by-step explanation:

Since sides of rectangle are at right angle to each other,

Applying Pythagoras theorem on the triangle whose sides are the sides of the rectangle ie, 15cm and 8cm and diagonal is hypotenuse.

hence,

(Diagonal)^2=15^2+8^2=225+64=289

Diagonal=17cm

Cheers!

Answer 2

Step-by-step explanation:

17 cm. Use pythagoras theorem.

l=root of 15 square + 8 square

l =root of 225+64=root of 289

l =17 cm. Since the diagonal form a right angled triangle. Use pythagoras theorem.
