Question

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

Answer 1

Answer:

The length of diagonal of a rectangle whose sides are 15 cm and 8 cm is 17 cm.

Step-by-step explanation:

If the sides of the rectangle are 15 cm and 8 cm

Length = 15 cm

breadth = 8 cm

Find the length of the diagonal of a rectangle.

By using Pythagoras theorem

$(diagonal)^2 = (Length)^2 + (breadth)^2$

$(diagonal)^2 = 15^2 + 8^2$

$= 225 + 64$

$= 289$

$(diagonal)^2 = \sqrt{289}$

Diagonal = 17cm

So, the length of diagonal of a rectangle whose sides are 15cm and 8cm is 17 cm.
