Given: the approximate height, h, in meters, travelled by golf balls hit with two different clubs over a horizontal distance of d meters is given by the functions: 
To find: distances when the ball is at the same height when either of the clubs are used. Also, to find this height

If the face is a square, then (l*l)
If the face is a triangle, then (b*h)(1/2)
If the face is a rectangle, then (l*w)
If the face is a circle, then (r²)(3.14)
You can then add all these faces up to get the total surface area of the prism.
If perimeter is 60 so the side is 60 ÷ 3 = 20
Now we can apply the area formula for triangles;
