Answer:

20300m^2

Step-by-step explanation:

first try to imagine the shape bisected into a rectangle and a triangle

to find the missing part of the triangle or the bottom side you need to subtract 70m from 140 m

140m-70m=70m this will be the base of your triangle

now you need the side

230m-60m=170

triangle formula base x height/ 2

70m x 170m=a

11900m=a

now the rectangle

base x height=a

60m x140m=a

8400m=a

finally add the two quantities together

8400m+11900m=a

20300m^2=a
