Answer :
[tex]A-pario\ area\\
A=3.6*3=10.8m^2\\
A_2-slab\ area\\
A_2=60cm*60cm=3600cm^2=0.36m^2\\
0.36m^2*32=11.52>10.8\\

8.63*32=276.16-total\ cost[/tex]
if Mathew has bought 32 slabs , he has enough paving slabs to cover the patio and £276.16 is the total cost of the 32 paving slabs.
What is a Rectangle ?
A rectangle is a polygon with 4 sides , in which opposite sides are parallel and equal .
It is given that the patio has length of 3.6 m and width of 3 m
Each paving slab is a square having side 60 cm or .6 m
Area of a rectangle is given by
length * width
3.6*3
10.8 m²
Area = 10.8 m²
Area of a slab = 0.6 *0.6 = 0.36 m²
No. of slabs needed = n
10.8 = 0.36* n
n = 30 slabs
So if Mathew has bought 32 slabs , he has enough paving slabs to cover the patio.
If the paving cost costs £8.63
The total cost for 32 slabs will be 32 * £8.63
= £276.16
