Ali has a rectangular pool around which he wants to construct a fence. The pool is 10 m long and 6 m wide, and he wants the fence to be 2 m from the edge of the pool on all sides.

How many metres of fencing will he need

10 + 4 = 14

6 + 4 = 10

P = 2L + 2W

P = 2(14) + 2(10)

P = 48 m

To determine the amount of fencing Ali will need, we can calculate the perimeter of the rectangular pool plus the extra 2 meters on each side.

The formula for finding the perimeter of a rectangle is P = 2(length + width), where P represents the perimeter, length is the longer side, and width is the shorter side.

Given that the pool is 10 meters long and 6 meters wide, we can plug these values into the formula:

P = 2(10 + 6)
P = 2(16)
P = 32

So, the perimeter of the rectangular pool (including the extra 2 meters on each side) is 32 meters.

Therefore, Ali will need 32 meters of fencing.
