A path of width 2 meters runs around and outside a square plot of side 10 meters. then the area of the path is what square meters I am 7th class

area of the path = 96 m²

Step-by-step explanation:

See attached diagram.

The green square is the square plot of side 10 m.

The grey is the path of width 2 m running around the outside of the square.

The easiest way to calculate the area of the path is to work out the entire area of the path and square plot, then subtract the area of the green square from it.

Area of a square = (side length)²

Area of green square = 10² = 10 x 10 = 100 m²

We are told that the width of the path is 2 m, so the side length of the square incorporating the path AND the green square will be:

side length of green square + 2 + 2 = 10 + 2 + 2 = 14 m

Therefore, entire area = 14² = 14 x 14 = 196 m²

To find the area of the path only:

entire area - area of green square = 196 - 100 = 96 m²

So the area of the path is 96 m²

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
