To find the area of a figure like this, first split this into two shapes to make things simpler: a 10 by 8 rectangle, and a triangle with a height of 5 and a base of 4. To find the dimensions of the triangle, notice that the base of the entire figure is 12 and once you split the figure into a rectangle and a triangle, you get one side that is 8 which means the base of the triangle must be 4. Now that we know the dimensions of each figure, start by finding the area of each one. To find the area of the rectangle, multiply its length by its width, or 10*8. This would give you 80. Then, find the area of the triangle, which is multiplying its base and height and dividing it by two. This would be (4*5)/2. This would equal 10. Now that we have the area of both the sections in the figure, add them together and you get your answer as 90.

Answer: C. is the right answer.


Step-by-step explanation:

Given: The cost of a chessboard at Odyssey Gifts is $6.

The function F(x) = 6x gives the cost of x chessboards.

Since x is the number of chessboards, thus the domain of the function should be the set of whole numbers.

Therefore, Domain= {0,1,2,3,4,5,....................}

when we put the values for x from the domain in the function we get values multiples to 6.

therefore range of the function={0,6,12,18,24,30,......}

Hence, C is the right option.
