square tiles of size 10 cm x 10 cm. Find the number of tiles required to cover the floor.
​

Answer 1

Step-by-step explanation:

length of rectangle= 5m20cm =520cm

breadth of rectangle= 3m70cm=370cm

area of rectangular courtyard=length×breadth

=520×370=182400cm²

area of square tile =side×side

=10×10= 100cm²

no. of tiles required

=area of rectangular courtyard/area of square

= 182400/100

=1824

the no. of tiles required are 1824
