Here are a few sample questions going over area of a rectangle. Question 1: Which formula is used to calculate the perimeter of a rectangle?
A rectangle has two equal lengths and two equal widths. In order to find the perimeter, or distance around the rectangle, we need to add up all four side lengths. This can be done efficiently by simply adding the length and the width, and then multiplying this sum by two since there are two of each side length.
Calculate the perimeter of the given rectangle. We can see that the length is The perimeter of the rectangle is 44 feet. Determine the perimeter of the rectangle if its area is 64 m 2 and its length is 16 m. In order to determine the perimeter of the rectangle, we first need to determine the width w.
The perimeter of the rectangle is 40 meters. The side lengths of a rectangular sandbox in Sunnyland Park are 15 feet and 8. Determine the perimeter of the sandbox. We know that the length is 15 feet and the width is 8. Use area formulas for these simpler shapes to help you find all the side lengths of the complex shape.
Not Helpful 7 Helpful No, the "oddness" of the shape makes it impossible to know the perimeter without more information. Not Helpful 2 Helpful 6. Let L be the length. Then L - 4 is the breadth.
Solve for L. The breadth will be 4 less than L. Not Helpful 5 Helpful To find the perimeter of a rectangle with a trinomial equation as the area, you'll need to factor this equation to get the sides. Once you've factored the equation, you can then add the sides to find the perimeter. Not Helpful 8 Helpful 8. A rectangle has a ratio of The area is square meters. What is the perimeter? Not Helpful 10 Helpful 9. How do I find the perimeter of a rectangle if I have the area, x squared - 81, and that's it?
If you assume that the length and width are both 9, you could easily find the perimeter. However, you can't really assume the length and width are each 9, so you don't actually have enough information to calculate the perimeter.
Not Helpful 9 Helpful No, if you don't know any of the sides, you can't find the perimeter. Not Helpful 11 Helpful 7. What is the perimeter of a rectangle that has one of the sides 7 m in length and the area is m squared?
Divide the area by the length. That gives you the width. Find the perimeter by adding twice the length to twice the width. Not Helpful 8 Helpful 6.
