To find the area of Field C, we need to use the Pythagorean Theorem.
The Pythagorean Theorem states that in a right triangle, the sum of the squares of the lengths of the two legs (a and b) is equal to the square of the length of the hypotenuse (c).
Therefore, we can use this theorem to find the length of the hypotenuse of Field C, which will give us the number of squares inside Field C.
Let's assume that the length of one side of the square grid is x.
In Field A, we counted a total of n squares, so the length of one side of Field A is √n.
In Field B, we counted a total of m squares, so the length of one side of Field B is √m.
Using the Pythagorean Theorem, we can set up the following equation:
(x^2 + (√n)^2) + (x^2 + (√m)^2) = (2x)^2
Simplifying the equation, we get:
x^2 + n + x^2 + m = 4x^2
2x^2 + n + m = 4x^2
Combining like terms, we get:
2x^2 - 4x^2 = -n - m
-2x^2 = -n - m
Dividing both sides by -2, we get:
x^2 = (n + m)/2
Taking the square root of both sides, we get:
x = √((n + m)/2)
Now that we have the length of one side of the square grid, we can find the area of Field C.
The area of Field C is the total number of squares inside Field C, which is equal to the length of one side of the square grid squared.
Therefore, the area of Field C in acres is (√((n + m)/2))^2.
Write the area of Field C on your worksheet.
Farmers need to know the area of their land in order to plan for growing their crops.
Farmers measure the size of their fields in acres. One acre is equal to 4,840 square yards. In the diagram on the worksheet, each of the squares in the grid represents one acre. Count the number of acres inside Fields A and B to find their measure, and then use that information to find the size of Field C.
