A floor 3.2m long and 2.8 m wide is to be covered with square shaped tiles of length 10cm. Find the coast of flooring if the coast tiles is Rs 150 per 100 tile.

1344

Step-by-step explanation:

100cm = 1 m

Convert the dimensions of the floor to cm = Area of a rectangle = length x breadth =  320 x 280 = 89,600m²

Area of a square = length² = 10cm² = 100cm²

Number of tiles that would be needed = area of floor / area of square

89,600cm² / 100cm² = 896

Cost of one tile = rs 150 / 100 = 1.5

Cost of 896 tiles = 1.5 x 896 = 1344

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
