Question

Suresh is having a garden near Delhi. In the garden, there are different types of trees and flower plants. One day due to heavy rain and storm one of the trees got broken as shown in the figure.
The height of the unbroken part is 15 m and the broken part of the tree has fallen at 20 m away from the base of the tree.
Using the Pythagoras answer the following questions:​

Answer 1

Answer:

Use the pythagoras theorem.

Step-by-step explanation:

Check the figure.

The length of the standing part of the tree = 15 m

Length of the base = 20 m

To find: Hypotenuse or the longest side.

Using Pythagoras theorem,

$ab^{2} + bc^{2} = ac^{2}$

Where, ab = 15 m

bc = 20

$15^{2} + 20^{2} = ac^{2}$

225 + 400 = $ac^{2}$

625 = $ac^{2}$

$\sqrt{625}$ = ac

∴ ac = 25

Answer 2

Answer:

Step-by-step explanation:

Use the pythagoras theorem.

The length of the standing part of the tree = 15 m

Length of the base = 20 m

To find: Hypotenuse or the longest side.

Using Pythagoras theorem,

Where, ab = 15 m

bc = 20

225 + 400 =  

625 =  

= ac

∴ ac = 25
