For triangle, A = 0.5 * l * h {area word problem}, where A is area, h is height, and l is side length. For rectangle, A = l*h, where A is area, and l h are side lengths. For circle, A = pi * r^2, where A is area, and r is radius.
P + P * r^t = T {interest word problem} {savings word problem} {investment word problem}, where P is principal, t is time, r is rate, and T is total.
For triangle, p = a + b + c {perimeter word problem}, where p is perimeter, and a b c are side lengths. For rectangle, p = a + b + c + d, where p is perimeter, and a b c d are side lengths. For circle, p = 2 * pi * r, where p is perimeter, and r is radius.
d = v*t {uniform motion word problem} {rate word problem} {time word problem} {distance word problem}, where d is distance, v is speed, and t is time. vf^2 = vi^2 + 2 * a * ds, where ds is distance, vf is final speed, vi is initial speed, and a is acceleration.
For box, V = l*h*w {volume word problem}, where V is volume, and l h w are side lengths. For sphere, V = (4/3) * pi * r^3, where V is volume, and r is radius.
