A 2m wide path is made around a square pound of area 6400 m². (a) Find the area of the path.
(b) How many tiles are required to pave on the path by the tile of area 0.40 m²? Find it.
(c) If the cost of a tile is Rs. 7.50, how much total cost will be required to pave the tiles on the path? Find it.

a) 656m^2 b) 1640 tiles c) 12300

Step-by-step explanation:

a) Area of path=Area of park with path - Area of park

Area of path=(84)^2-(80)^2=656m^2

b) Tiles needed= 656/0.4=1640 tiles

c) Cost=7.5*(1640)=123000

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
