$\huge{\green{\underline{\underline{Answer:-}}}}$

Given:

Rajinikanth drove

• 15 kilometre straight towards North
• Then turned east and covered 8 kms
• Turned to left and covered 1 km
• Again turned left and drove for 20 km

To find:

Distance and direction = ?

Explanation:

Refer 3 attachment. If want to see swipe on attachment to understand more

PE is distance between office and house, we have to find length of PE

In rectangle QRST,

Length of TS = Length of QR = 8 km

Length of ET = Length of SE - Length of TS

Length of ET = 20 - 8

Length of ET = 12 km

Length of QT = Length of SR = 1 km

Length of PT = Length of QT + Length of PQ

Length of PT = 1 + 15

Length of PT = 16 km

In △PTE

$\\ \\ PE² = ET² + PT² \\ \\ PE² = 12 {}^{2} + 16 {}^{2} \\ \\ PE² = 144 \: + 256 \\ \\ PE² = 400 \\ \\ PE = \sqrt{400}$

$\\ \\ PE = 20 \: kms$

Answer:

Thus, the distance between home and office is 20 kms and his office is in North West direction rom home

Note:

• NW = North West
• NE = North East
• SE = South East
• SW = South West
• W = West
• E = East
