Question

225 square shaped mosaic tiles, each of area 1 square decimetre exactly cover a square
shaped verandah. How long is each side of the square shaped verandah?​

Answer 1

Each side of the square shaped verandah =15 dm= 1.5 m

Step-by-step explanation:

1. Given

  Area of one tiles = 1  $\mathbf{(dm^{2})}$

  Number of tiles = 225

2. So

  Area of 225 tiles = $\mathbf{1\times 225(dm^{2})= 225 (dm^{2})}$

3. Here it is given all tiles cover verandah.

  So area of verandah $\mathbf{= 225 (dm^{2})}$

4. We know that

  Area of square $\mathbf{=Side^{2}}$

   Area of verandah $\mathbf{= 225 (dm^{2})}$

   $\mathbf{Side^{2}=225}$

   $\mathbf{Side=\sqrt{225}}$

  So

  $\mathbf{Side=15 dm=1.5 m}$

5. So

   Side of verandah = 15 dm =1.5 m
