The side lengths of a square if its area is 81 meters squared is: 9 meters.

1,350 cm squared To find the area of a rectangle you just use the equation l x w = area squared (length times width = area squared). So you would just multiply 45 and 30

If you're using 30cm x 30cm tile then it cover 900 cm area using 1 tile and your area is 12m x 12m=144m x 100 = 14400cm. Now 14400cm / 900cm = 16.You need 16 pcs of 30cm x 30cm tiles.

Whenever different units are specified in a problem, we need to convert them to one common unit. The total area is given in square meters but the tile measurements are given in cm. So let's convert the tile measurements to meters. Why not convert the total area to square centimeters. Sure you can, only thing is all measurements must be in the same unit. No mixing of units. So the tile size in meters is 0.3m x 0.3m and so the area of a single tile is 0.09 square meter. Divide total area by area of a single tile and you will get the number of tiles needed. Thus the number of tiles needed is 18.5/0.09 = 205.5 tiles, make it 206 tiles.

This does not make sense. Meters squared is a unit of area, not distance.

work it out

300 mm = 0.300 meters and 450 mm = 0.450 meters. Therefore, the area of each tile in square meters is 0.300 X 0.450 = 0.135 square meters. Therefore, the smallest number of tiles that can cover an area of 13 square meters is 13/0.135 or at least 97 tiles.

We, know that tiles are square.So, first calculate area of tiles =side X side .Now , no. of tiles = area of room /area of tiles .Hence,no.of tiles =2500 X 2500 /25 X25 =10000
