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.
He want to pave the area around the pool and within the fence. How many square metres of paving bricks will he need?
14*10 - 10*6
To find the total area of the paving bricks needed, we first need to calculate the dimensions of the fenced area.
The length of the fence is the length of the pool plus twice the distance from the edge of the pool:
Length of the fence = 10 m + 2 * 2 m = 14 m.
Similarly, the width of the fence is the width of the pool plus twice the distance from the edge of the pool:
Width of the fence = 6 m + 2 * 2 m = 10 m.
Now, we can find the area of the fenced area:
Area of the fenced area = Length of the fence * Width of the fence
= 14 m * 10 m
= 140 m².
Therefore, Ali will need 140 square meters of paving bricks for the area around the pool and within the fence.
