Find the area of the left polygon and find the area of the right polygon

106 m²

Step-by-step explanation:

we can see in the figure that it is made up of one square and one trapezium

Formula to calculate the area of this polygon

Area of square + Area of trapezium

Area of square

side²

5²

25

Area of trapezium

here a and b is the parallel sides

        h is the height of trapezium

(6+3)(9)

(9)(9)

81

Area of the polygon

25 + 81

106

Answer with step-by-step explanation:

We are to find the area of the shaded region which we can break down into smaller shapes and make it easier to find their areas.

We have a small square at the left side with side length 3 meter. At the right side, we have a rectangle and a triangle.

Area of left polygon = = 9 m

Area of right polygon = Area of rectangle + Area of triangle

Area of right polygon = = 81 m

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
