Explanation:

in this figure you can observe 1 cube and 3 half cirles

the flield of the square would by using a formula a(lenght) * b(height)

in this case it would be 10m * 10m = 100m

and the formula for a cirle would be

A = pir^2

knowing that we can connect two of the halfs and make a cirle with a radius of 5

A= pi 5^2

A= pi 25

25pi approximatly equals to 78.53982m

knowing that information we can devide that value by 2 and get the value of the 3rd half cirlce

which is 39.26991m

than we add all the values we collected

39.26991m + 78.53982m + 100m = 217.80973 m

Answer: Area: (100+75π/2)cm^2 Perimeter: (10+75π/2)cm

Explanation:

Area of total shape

= square+3 semi-circles

=100cm^2 + 5*5πcm^2*3/2 = 100cm^2+75/2*πcm^2

= (100+75π/2)cm^2

Perimeter of shape

= 10cm + 25/2π*3cm

= (10+75π/2)cm
