The area of a rectangle equals its length times the width (base times the height). A = length x width = lw or A = base x height = bh Area of a Rectangle

Length (l) Width (w) Area of a Rectangle

The area of a square equals its side times side. Area of a Square

Side (s) Area of a Square

The perimeter of a rectangle equals the sum of its length and width multiplied by two. Perimeter of a Rectangle

Length (l) Width (w) Perimeter of a Rectangle

The perimeter of a square equals 4 times the length of a side. Perimeter of a Square

Side (s) Perimeter of a Square

The area of a parallelogram equals the product of its base (b) and height (h). The base and height must form a right angle (90º). Area of a Parallelogram

base (b) height (h) right angle (90º) Area of a Parallelogram

The area of a triangle equals half of the product of base (b) and height (h). Its base and height must form a right angle (90°). Area of a Triangle

right angle (90º) base (b) height (h) Area of a Triangle

 Surface area is the total area of the surfaces of a solid figure.  Surface area is measured in square units ( ) Top Right Front Surface Area

TOP BACK FRONT RIGHT LEFT BOTTOM Surface Area – Rectangular Prism

FRONT RIGHT SIDE LEFT SIDE TOP BACK BOTTOM Surface Area – Rectangular Prism

 TOP is congruent to BOTTOM  RIGHT is congruent to LEFT  FRONT is congruent to BACK Surface Area – Rectangular Prism

 Volume is the measurement of the number of cubic units ( ) that make up a solid figure.  Volume measures how much room a solid figure takes up in space.  Volume also measures how much room is in a solid figure (capacity). Volume – Rectangular Prism

The volume of a rectangular prism equals its length times width times height. Volume = length x width x height Volume – Rectangular Prism

LENGTH WIDTH HEIGHT Volume – Rectangular Prism

length (l) width (w) height (h) Volume – Rectangular Prism

Side Volume = side x side x side Volume = s³ Volume – Cube

Volume = side x side x side = side³= s³ Volume = 5 inches x 5 inches x 5 inches = 125 inches³ 5 inches Volume – Cube
