a) £ 43.96
A = 2 x 2.2
A = 4.4 m^2
4.4 x 9.99 = 43.956
b) 3.21 m^2
First, find the area of the entire floor.
A = 2 x 2.2 = 4.4 m^2
Then, find the area of the bath.
A = 1.7 x 0.7 = 1.19 m^2
Finally, subtract the area of the bath from the area of the entire floor to find the area that is re-tiled.
4.4 - 1.19 = 3.21
Hope this helps!! :)
