a = 8,059.52 m²

Step-by-step explanation:

Area of square

a = s²

a = 56²

a = 3,136

Area of circle

a = πr²

a = 3.14(56/2)²

a = 2,461.76

Area of 4 semicircles = area of 2 circles

a = 2,461.76 * 2

a = 4,923.52

Total area

a = 3,136 + 4,923.52

a = 8,059.52 m²

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)
