I guess you need to find the area :
Area of the figure = Square area + half of
circle area
A = ( length )^2 + 1/2 × pie × ( radius)^2
A = ( 10 )^2 + 1/2 × pie × ( 10/2 )^2
A = 100 + 1/2 × pie × 25
A = 100 + 12.5 pie
____________________________
If pie = 3 : | If pie = 3.14 :
|
A = 100 + 12.5 × 3 | A = 100 + 12.5 × 3.14
|
A = 100 + 37.5 | A = 100 + 39.25
|
A = 137.5 m^2 | A = 139.25 m^2
