Question

$question \:$
${4}^{2} + {10}^{2} - \frac{8}{12}$
please solve this ​

Answer 1

Step-by-step explanation:

• 16+100-8/12
• 116-8/12
• 1392/12-8/12
• 1384/12
• =115.33

Answer 2

The length of the each side of water tank =1.5m=150cm

As it is given that base is not covered with tiles so, five sides of the tank are 

covered with tiles.

Therefore,

Surface area of water tank =5a2=5(150)2=112500 cm2

Side of tile =25 cm

Area of tile =252=625 cm2

Number of tiles to cover five sides of the tank =625112500=180

Now,

Cost of one dozen tiles =Rs.360

Hence, total cost of 180=12360×180=Rs.5400
