Example Question #56 : Rectangles
What is the area of the figure below?
To find the area of the figure above, we need to slip the figure into two rectangles.
Using our area formula, , we can solve for the area of both of our rectangles
To find our final answer, we need to add the areas together.
Example Question #251 : Hspt Mathematics
What is the area of a triangle with a side lengths of 5?
Cannot be determined
Cannot be determined
The area of a triangle is found with the equation
.
Since we do not have the height, we cannot answer the question.
Example Question #252 : Hspt Mathematics
What is the area of a triangle with a base of 22 cm and a height of 9 cm?
Use the area of a triangle formula
Plug in the base and height. This gives you .
Example Question #253 : Hspt Mathematics
What is the circumference of a circle with a radius of 5?
The formula for circumference is or .
Since we are given the radius, we will use .
Example Question #254 : Hspt Mathematics
What is the perimeter of a square with a side length of 4?
The formula for the perimeter of a square is , where is the length of one side of the square.
So
Example Question #255 : Hspt Mathematics
If the perimeter of a rectangle is 40, and the width of the rectangle is 8, what is the length of the rectangle?
The formula for the perimeter of a rectangle is , where is the length of the rectangle and is the width.
Plug in the numbers that we are given into the equation.
Example Question #256 : Hspt Mathematics
What is the perimeter of a rectangle with a base of 4 and a height of 8?
When searching for the perimeter of a rectangle we are looking for the sum of the lengths of all of the sides enclosing the figure. In this case there are four sides, two that are the base and two that are the height. To find the perimeter we add all four of them together.
Therefore the equation for the perimeter of a rectangle is
In this case the equation looks like this
Multiply the numbers together
Then add them to get the answer
Example Question #257 : Hspt Mathematics
What is the height of a rectangle with a perimeter of 30 and base of 12?
The perimeter of a rectangle is the sum of four sides, two that are the base and two that are the height. To find the perimeter we add all four of them together.
Therefore the equation for the perimeter of a rectangle is
In this example we plug in the base and the perimeter so the equation looks like this
Perform the multiplication to get
Subtract from both sides to arrive at
Then divide by 2 to find the height
The answer
Example Question #258 : Hspt Mathematics
What is the perimeter of a square with a side legnth of 8?
When searching for the perimeter of a square we are looking for the sum of the lengths of all of the sides enclosing the figure. In this case there are four sides that are all equal length. To find the perimeter we add all four of them together or multiply the side length by four.
In this example the equation looks like this:
Multiply the numbers together to get .
Example Question #259 : Hspt Mathematics
What is the radius of a circle with a circumference of ?
To find the radius of a circle given the circumference we must first know the equation for the circumference of a circle which is
Then we plug in the circumference into the equation for yielding
We then divide each side by :
We then have the answer for which is .
