AREA OF A RECTANGLE

A rectangle is a plane surface having four sides. The opposite sides are equal

and parallel. All angles are right angles.

Look at the rectangle below.

(1) Side a side b and is parallel.

(2) Side c side ____ and is

parallel.

(3) All angles are __________

angles, or 90.

Consider this rectangle and suppose it to be divided as shown.

(4) Each of the small squares is 1 inch on a side. You can call each an inch

square, and you say it has an area of one square inch. You say the area of this

rectangle is 12 square inches because it is made up of _________________ squares,

each measuring 1 inch. In this problem you can see that to find the area of the

rectangle, you can count the square inches or simply multiply one side times the

other; that is, multiply length times width.

3 inches x 4 inches ____________ square inches

Now you understand by the formula for the area of a rectangle is:

Area Length x Width A = L x W
