Answer:
lawn area = 68 m²
Step-by-step explanation:
The overall length of the rectangle is 7+7 = 14 m, so its area is ...
A = LW = (14 m)(10 m) = 140 m²
The area of the trapezium is ...
A = (1/2)(b1 +b2)h = (1/2)(7 m +5 m)(10 m) = 60 m²
The area of the triangle is ...
A = 1/2bh = 1/2(3 m)(8 m) = 12 m²
The lawn area is that part of the rectangle that is not flower bed or vegetable patch, so is ...
lawn area = 140 m² -12 m² -60 m²
lawn area = 68 m²
