Samir was standing facing East. He turned to his right and walked 5 metres, again turned to his right and walked 7 metres.
Then he turned to his left and walked 4 metres. Which direction
is he facing now?

He is now facing to the south, this is because,

He is currently facing east, and right of east = south

Then one more right turn would give, right of south = west

Next, he turns left of west = south

So, he is now facing to the south direction

Thanks!

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
