Example Question #61 : Plane Geometry

Use the following square to solve the problem:

Square1

Find the perimeter.

Possible Answers:

Correct answer:

Explanation:

To find the perimeter of a square, we will use the following formula:

where a, b, c, and d are the lengths of the sides of the square.

 

Now, given the square

Square1

we can see the length is 5cm.  Because it is a square, all sides are equal.  Therefore, all sides are 5cm.  So, we will substitute.

Example Question #62 : Geometry

The perimeter of a square is 24in.  Find the length of one side.

Possible Answers:

Correct answer:

Explanation:

To find the perimeter of a square, we can use the following formula:

where a is the length of one side.  Because a square has 4 equal sides, we can take 4 times the length of one side.  So, to find the length of one side, we will solve for a.

We know the perimeter of the square is 24in.  So, we will substitute.  We get

 

 

 

 

Therefore, the length of one side of the square is 6in.

Example Question #4 : How To Find The Area Of A Rectangle

John needs a tablecloth that covers his entire dining room table. The tabletop measures 4 feet by 7 feet. Which of the following tablecloths should John buy? 

Possible Answers:

Correct answer:

Explanation:

The tablecloth measurements are areas, shown by the  units in the answer choices. Since the tabletop is 4 ft by 7 ft, John needs a tablecloth with an area of AT LEAST .  

 is the only answer choice that meets that requirement. 

Example Question #5 : How To Find The Area Of A Rectangle

What is the area of the above rectangle?

Possible Answers:

Correct answer:

Explanation:

To find the area of the rectangle, multiply the longer side (12) and the shorter side (3) together. 

Example Question #6 : How To Find The Area Of A Rectangle

A rectangle has a perimeter of . One of its sides has a length of .

What is the area of the rectangle?

Possible Answers:

Correct answer:

Explanation:

The perimeter of a figure is the sum of the lengths of all its sides. Every rectangle has two sets of two equal-length sides. One set of sides is  each, or  when added together.

We subtract  from the total  perimeter to find the lengths of the remaining sides.

Since there are two remaining sides, the length of each of the remaining sides must be .

The area of a rectangle is given by multiplying the length of its longer side by the length of its shorter side.
