  a) Find the width of the path.
  b) The path is to be covered with square concrete slabs. Each corner of the path is covered with a slab whose side is equal to the width of the path.The rest of the path is covered with slabs of side 50cm. The cost of making each corner slab is Shs.600 while the cost of making each smaller slab is shs.50.
  Calculate;
  i) The number of the smaller slabs used.
  ii) The total cost of the slabs used to cover the whole path.
