A rectanglar school yard is 280 meters by 245 meters is to be fenced. How many meters of fencing will be required to fence it completely?

You're way off.

P = (2 * 280) + (2 * 245)

P = ?

P = 2L + 2W

P = ?

525

1050m

1050

To find the total number of meters of fencing required to completely fence a rectangular school yard, we need to calculate the perimeter of the yard. The perimeter of a rectangle is found by adding the lengths of all four sides.

In this case, the length of one side is 280 meters, and the length of the adjacent side is 245 meters. We can add these two sides together to get the total length of the longer sides of the rectangle: 280 + 245 = 525 meters.

Since there are two longer sides, we need to multiply this length by 2 to account for both sides: 525 * 2 = 1050 meters.

Next, we need to calculate the total length of the shorter sides of the rectangle. Each shorter side has a length of 245 meters, and since there are two shorter sides, we multiply this length by 2 as well: 245 * 2 = 490 meters.

Finally, we add the total length of the longer sides to the total length of the shorter sides to get the total perimeter of the rectangular yard: 1050 + 490 = 1540 meters.

Therefore, 1540 meters of fencing will be required to completely fence the rectangular school yard.
