Mathematics Formula Sheet - Key Geometry, Area, Perimeter, and Algebra Formulas

Sep 14, 2026

Mathematics Formula Sheet consolidates core geometry formulas for area and perimeter, including common shapes such as squares, rectangles, triangles, trapezoids, parallelograms, and circles, along with circumference. It also provides surface area and volume relationships for key solids like rectangular prisms, prisms, cylinders, pyramids, cones, and spheres. The sheet further includes foundational algebra and data concepts covering mean and median, slope and slope-intercept and point-slope forms, quadratic standard form and quadratic formula, Pythagorean theorem, simple interest, total cost, and distance formula.

Mathematics Formula Sheet Area of a: | square |
A = s2 | | --- | --- | | rectangle | A = lw | | parallelogram |
A = bh | | triangle | A = 12 bh | | trapezoid |
A = 12 h(b1 + b2) | | circle | A = πr2 | Perimeter of a: | square | P = 4s | | | --- | --- | --- | | rectangle | P = 2l + 2w | | | triangle | P = s1 + s2 + s3 | | | Circumference of a circle
Surface area and volume of a: | C = 2πr OR C = πd; π ≈ 3.14 | | | rectangular prism | SA = 2lw + 2lh + 2wh | V = lwh | | right prism | SA = ph + 2B | V = Bh | | cylinder | SA = 2πrh + 2πr2 | V = πr2h | | pyramid | SA = 12 ps + B | V = 13 Bh | | cone | SA = πrs + πr2 | V = 13 πr2h | | sphere | SA = 4πr2 | V = 43 πr3 | | Data | (p = perimeter of base with area B; π ≈ 3 . 14) | | --- | --- | | mean |
mean is equal to the total of the values of a data set, divided by the number of elements in the data set | | median
Algebra | median is the middle value in an odd number of ordered values of a data set, or the mean of the two middle values in an even number of ordered values in a data set | |
slope of a line |
y2 − y1 m = ~~ ~~x2 − x1 | | slope-intercept form of the equation of aline | y = mx + b | |
point-slope form of the equation of a line |
y – y1 = m(x – x1) | | standard form of a quadratic equation | y = ax2 + bx + c | |
quadratic formula |
x =
–b ±√b2– 4ac
2a | | Pythagorean theorem | a2 + b2 = c2 | |
simple interest |
I = Prt
(I = interest, P = principal, r = rate, t = time) | | distance formula | d = rt | |
total cost |
total cost = (number of units) × (price per unit) | | | | [GED.com](GED.com) GED® and GED Testing Service® are registered trademarks of the American Council on Education.
