Answer:
12/32 divide by 4 and get 3/8 you can’t simplify any further after that

Step-by-step explanation:
One is asked to find the distance between two points on a coordinate plane. The easiest way to do so is to use the distance formula, this formula is the following:
![D=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2](https://tex.z-dn.net/?f=D%3D%5Csqrt%7B%28x_1-x_2%29%5E2%2B%28y_1-y_2%29%5E2)
Where (
) and (
) are the points which one needs to find the distance between. In this case, these points are as follows:
![k\ (-3,5)](https://tex.z-dn.net/?f=k%5C%20%28-3%2C5%29)
![j\ (-8, -7)](https://tex.z-dn.net/?f=j%5C%20%28-8%2C%20-7%29)
Substitute these points into the formula and solve for the distance between these points,
![D=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2](https://tex.z-dn.net/?f=D%3D%5Csqrt%7B%28x_1-x_2%29%5E2%2B%28y_1-y_2%29%5E2)
![D=\sqrt{((-3)-(-8))^2+((5)-(-7))^2](https://tex.z-dn.net/?f=D%3D%5Csqrt%7B%28%28-3%29-%28-8%29%29%5E2%2B%28%285%29-%28-7%29%29%5E2)
Simplify,
![D=\sqrt{((-3)-(-8))^2+((5)-(-7))^2](https://tex.z-dn.net/?f=D%3D%5Csqrt%7B%28%28-3%29-%28-8%29%29%5E2%2B%28%285%29-%28-7%29%29%5E2)
![D=\sqrt{(-3+8)^2+(5+7)^2](https://tex.z-dn.net/?f=D%3D%5Csqrt%7B%28-3%2B8%29%5E2%2B%285%2B7%29%5E2)
![D=\sqrt{(5)^2+(12)^2](https://tex.z-dn.net/?f=D%3D%5Csqrt%7B%285%29%5E2%2B%2812%29%5E2)
![D=\sqrt{25+144}](https://tex.z-dn.net/?f=D%3D%5Csqrt%7B25%2B144%7D)
![D=\sqrt{169}](https://tex.z-dn.net/?f=D%3D%5Csqrt%7B169%7D)
![D=13](https://tex.z-dn.net/?f=D%3D13)
The two numbers that add to make twenty and have a difference of 4 are 12 and 8
Answer:
720 m²
Step-by-step explanation:
Area = base × height
= 12 × 6
= 72 mm²
≈ 720 m² (1 mm = 10 m)
