Answer:
Step-by-step explanation:
Distance can be calculated using this formula:
where (x₁, y₁) and (x₂, y₂) are the points. We are given the points (6, -9) and (1, 3). Therefore:
Substitute the values into the formula.
Solve inside the parentheses.
Solve the exponents.
- (-5)²= -5*-5 =25
- (12)²= 12 *12= 144
Add and take the square root.
The distance is 13.
Answer:
The area of the backyard is 18 cm
Answer: 67.27
Step-by-step explanation:
7.1 x 7.1 for the square = 50.41
7.1 divided by 2 = 3.55
3.55 x 4.75= 16.86
Normally here you would divide by 2, but you don’t need two because there is 2 triangles that are the same
Add the 50.41 and the 16.86 and you have your answer!
