Answer:
74.7 sq. ft.
Explanation
The formula to find the area of a triangle is BH/2. First I make a line to make two triangles. Looking at the triangle on the right, both sides have 1 dash, meaning they have equal sides, so using the formula the area of that triangle is 5.12 sq. ft. Next we have the triangle on the left, and since it tells us that AB = 11.8 ft., we can use the formula and get 69.62 sq ft. Then we add both areas up to get the total area of the flowerbed which is 74.74 sq ft rounding to 74.7 sq ft.
