Perimeter = 2 X Lengths + 2 XWidthsP = 2(l + w)

ParallelogramArea = Base X Heighta = bhTriangleArea = 1/2 of the base X the heighta = 1/2 bhPerimeter = a + b + c(add the length of the three sides)

Trapezoid

Perimeter = a + b1 + b2 + cP = a + b1 + b2 + c

The distance around the circle is a circumference. Thedistance across the circle is the diameter (d). The radius(r) is the distance from the center to a point on the circle.(Pi = 3.14)d = 2rc = 2x pi x rA = pr

Rectangular Solid(Rectangular prism)Volume = Length X Width X HeightV = lwhSurface area = 2lw + 2lh + 2wh

PrismsVolume = Base X Heightv=bhSurface = 2b + Ph (b is thearea of the base P is theperimeter of the base)

Surface area

PyramidV = 1/3 bh (1/3 x area of the base x height

b is the area of the baseSurface Area: Add the area of the base to thesum of the areas of all of the triangular faces.The areas of the triangular faces will havedifferent formulas for different shaped bases.

ConesVolume = 1/3 pr2 x heightV= 1/3 pr2hSurface = pr2 + prsS = pr2 + prs=pr2 + pr
