Answer:
77.74 square feet
Step-by-step explanation:
1. We have to keep the triangle and the rectangle apart and find the area of each separately then add the areas together.
The formula for the area of a rectangle is height x width = area
So, 6.5 feet x 10.4 feet = 67.6 feet squared
The formula for the area of a triangle is height x width x (1/2) = area
So, 5.2 feet x 3.9 feet x (1/2) = 10.14 feet squared
Now, add the two areas together.
10.14 square feet + 67.6 square feet = 77.74 square feet
8 and 9, since square root of 64 is 8 and square root of 81 is 9, it is known that square root of 75 is between 8 and 9
Hence the maximum possible area is 2500 square meteres
Given the area of the rectangular garden expressed as;
The maximum area occurs when dA(x)/dx = 0
Next is to get the maximum area possible. Substitute x = 50 into the original function as shown;
Hence the maximum possible area is 2500 square meters
