the complete question in the attached figure
step 1
find the perimeter of the figure
perimeter of the figure=perimeter of trapezoid+perimeter square-300
perimeter of trapezoid=2*500+1100+300-----> 2400 m
perimeter square=4*300----> 1200 m
perimeter of the figure=perimeter of trapezoid+perimeter square-300
perimeter of the figure=2400+1200-300----> 3300 m
step 2
find the area of the figure
area of the figure=area of trapezoid+area square
area of trapezoid=(a+b)*h/2----> (1100+300)*300/2----> 210000 m²
area of square=300²----> 90000 m²
area of the figure=210000+90000-----> 300000 m²
the answer is
Is required 3300 m of fencing and 300000 m² of sod
