Answer:
13,5
Step-by-step explanation:
Find the length of the diagonal lines with Pythagorean theorem, and because it is already given that the lengths of the sides of the preformed shape are all equal, graph the 6th point with your information.
This figure is what we would call a composite figure. A composite figure is a shape that is made up of multiple other shapes. when looking at the pond and the border that surrounds it, we can see that this heart shape is made up of two semi circles and a square. To find the area of the border, we will use the area formulas for semi circles and for squares:
Semi Circle Area Formula:

÷
2
Square Area Formula: length x width
Pi = 3.14
Radius = Half of the diameter, in this case 6
After finding the area of each shape, we can subtract the 2 ft width to find the area of the flower bed border.
The answer is 125
To solve:
(3+2)=5. *Parentheses first*
5^3 = 125
You combine the like terms to get
2s^2y^2-4a^2sy+2a^4
