6 x 60 x 5 would be the equation and all of that put together would be 1,800 vehicles would pass by in an hour.

With right triangles you can use the equation a^2 + b^2 = c^2. Since both a and b are 7, that makes it 7^2 + 7^2 = c^2 and from there 49 + 49 = c^2 and then 98 = c^2. Then go find C, you find the square root of 98 which is 9.899494937 or rounded as 9.9
Keep in mind a^2 + b^2 = c^2 only works for right triangles, it won’t work for any other ones.
