How do I solve for the shaded area?

Option A:

Area of the shaded part = 99 cm²

Solution:

Length of the rectangle = 15 cm

Width of the rectangle = 9 cm

Area of the rectangle = length × width

                                    = 15 × 9

                                    = 135 cm²

Area of the rectangle = 135 cm²

Side of the square = 6 cm

Area of the square = side × side

                                = 6 × 6

                                = 36 cm²

Area of the square = 36 cm²

Area of the shaded part = Area of the rectangle – Area of the square

                                        = 135 cm² – 36 cm²

                                        = 99 cm²

Area of the shaded part = 99 cm²

Option A is the correct answer.

Hence the area of the shaded part of the figure is 99 cm².

step-by-step explanation:

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
