Answer:

840

Step-by-step explanation:

Given:

Tiles required = 700 tiles

size = 15cm × 10cm

To find:

Tiles required to cover

Solution:

Any two-dimensional shape's area is referred to as its area. Additionally, Surface Area refers to the area that any three-dimensional shape occupies.

For instance, a circle is a two-dimensional shape while a sphere is three-dimensional. The area occupied by a sphere, cuboid, cube, cylinder, cone, or hemisphere, for example, is known as surface area, whereas area refers to the area inhabited by a circle, rectangle, square, triangle, etc.

Square units are used to measure area.

Area of the tile before changing the form = 15 × 10 =150cm^{2}

\frac{AreaOfRoom}{AreaOfOneTile}=Number of tiles required

700=\frac{AreaOfRoom}{150}

Thus the area of room is 105000

So, the new area of one tile = 25×5=25cm^{2}

\frac{AreaOfRoom}{AreaOfOneTile}=Number of tiles required

=\frac{105000}{125} \\=840

Hence the correct answer is 840.
