Answer:
The plot is made up of a rectangle and a trapezium:
Total area = area of rectangle+area of trapezium
[tex]{ \tt{area = 2(l + w) + \frac{1}{2} h(a + b)}}[/tex]
substitute:
[tex]{ \tt{area = 2 (300 + 196) + \frac{1}{2} (300 - 196)(480 + 300) }} \\ \\ { \tt{area = 992 + 40560}} \\ \\ { \boxed{ \boxed{ \tt{ \: \: area = 41552 \: \: {m}^{2} \: \: }}}}[/tex]
