How much fencing is required for a school yard measuring 280 meters by 245 meters?

To determine how much fencing is required for a rectangular school yard measuring 280 meters by 245 meters, we first need to calculate the perimeter of the rectangle. The formula to find the perimeter (P) of a rectangle is:

[

P = 2 \times (length + width)

]

In this case, the length of the school yard is 280 meters, and the width is 245 meters. Plugging these values into the formula gives us:

[

P = 2 \times (280 + 245)

]

First, we sum the length and width:

[

280 + 245 = 525

]

Then, we multiply by 2 to find the perimeter:

[

P = 2 \times 525 = 1,050

]

This calculation shows that the total amount of fencing needed is 1,050 meters, making this the correct answer. The measurement takes into account the entire outer boundary of the school yard, thus providing the total length of fencing required to enclose the area completely.

The value 1,404 meters does not correspond to any calculation involving the perimeter of this rectangle, as it appears to result from a miscalculation or misunderstanding of
