Answer:
Step-by-step explanation:
m = 4
![y -y_{1}=m(x -x_{1})\\\\y - 4 = 4(x -[-1])\\\\y - 4 = 4(x + 1)\\\\y -5= 4x + 4\\\\y = 4x + 4 + 5\\y = 4x + 9](https://tex.z-dn.net/?f=y%20-y_%7B1%7D%3Dm%28x%20-x_%7B1%7D%29%5C%5C%5C%5Cy%20-%204%20%3D%204%28x%20-%5B-1%5D%29%5C%5C%5C%5Cy%20-%204%20%3D%204%28x%20%2B%201%29%5C%5C%5C%5Cy%20-5%3D%204x%20%2B%204%5C%5C%5C%5Cy%20%3D%204x%20%2B%204%20%2B%205%5C%5Cy%20%3D%204x%20%2B%209)
Use the formula
Area= base times height.
You're given that area =300cm^2 and base=20 cm.
Plug these into the equation to get 300=20 x height. Now, you just need to solve for height. To do this, you need to undo the multiplication of b x h by dividing the area by the base.
So, h = 300/20
Simplify for an answer of 15.
