What is the perimeter of a rectangle with an area of 250 square feet and length of 25 feet?
For a start at this question, find out how wide this rectangle must be. area (250) = length (25) x width (???) The area of a rectangle is its length times its width. We should divide the area by the length (25) to get the width. The answer is 10. Then we know that each long side is 25 and each short side is 10. We know that in a rectangle, the long sides are the same length and the short sides are the same width. In order to get the perimeter, we add 25 and 25 and 10 and 10. We get 70. So the perimeter is 70.
What is the perimeter of a rectangle with 14 centimeters and width 9 centimeters?
Perimeter is the length of a closed line around an area. A rectangle is an area. If each long side of the rectangle is 12 cm and each end of the rectangle is 9 cm, the total length is 14+14+9+9 or 46 cm.
A rectangle has a length of 10 centimeters and an area of 40 square centimeters what is the width of the rectangle?
1.10*X=402. Divide each side by 10:X=4 centimeters3. Check your answer 10*4=40The width of the rectangle is 4 centimeters
How do you work out an area of a parallelogram?
It is the same as the area of a rectangle, you simply x length by width. This is because the slanted edges kind of cancel each other out.
What is the area of a rectangle with a perimeter of 16cm?
Well, well, well, aren't we getting fancy with our geometry questions? If the perimeter of a rectangle is 16cm, that means the sum of all its sides is 16cm. Since a rectangle has two pairs of equal sides, we can divide 16cm by 4 to get each side length, which is 4cm. To find the area, you simply multiply the length and width, so the area of this rectangle would be 16 square centimeters.
How do you find length and width of a rectangle when peremiter is given?
You really can't unless you know something else about the length or width or even the area of the rectangle. You have 2 unknowns (length & width) & only one equation (perimeter). In order to find 2 unknowns you need 2 equations, that's why you need to know something else about the rectangle such as how the length & width are related to each or the area of the rectangle. Hope that helps.
How do you find the area of each face on a box?
Each face of a box is a rectangle . The area of a rectangle is (its length) times (its width). Measure the length and width of each face, and multiply (length times width). If you think about what you're doing, and plan it carefully, you only have to make three measurements and you'll have the whole box covered ... all six faces.

How do you find the unknown width of a rectangle?
It depends on what information you do have. The length and area, the length and diagonal, the length and perimeter, etc. Each set generates a different answer.
A rectangle has a perimeter of 26 feet the length and the width are each a whole number of feet Which is a possible area for this rectangle?
24 feet square feet
What is the perimeter of a rectangle with 14 centimeters and width 9 centimeters?
Perimeter is the length of a closed line around an area. A rectangle is an area. If each long side of the rectangle is 12 cm and each end of the rectangle is 9 cm, the total length is 14+14+9+9 or 46 cm.
If the area of a rectangle is 18 square inches and the length of the rectangle is twice it's width what is the length and width of the rectangle?
A rectangle with one side that is double the length of the other side can be seen as two squares beside each other, that are half the area of the original rectangle, in this case 18 square inches / 2 = 9 square inches. The side of a square is the square root of the area, in this case the square root of 9 square inches, which is 3 inches. Now think about the rectangle again. What we just counted was the side of a square that made up one half of the rectangle you wanted to calculate the area of. So the shorter side of the rectangle is the same as our square, and the longer side is double the length. So the width of the rectangle is 3 inches, and the length is 2 * 3 inches = 6 inches. Or: Area = length x width (A=lw) Area = 18 (in2) Width = w Length = twice width (2w) 18 = (2w)w 18 = 2w2 9 = w2 3 = w The width is 3 in., the length (2w) is 6 in.
A rectangle has a length of 10 centimeters and an area of 40 square centimeters what is the width of the rectangle?
1.10*X=402. Divide each side by 10:X=4 centimeters3. Check your answer 10*4=40The width of the rectangle is 4 centimeters
The length of a rectangle is 8 cm more than the width find the dimensions of the rectangle if the area is 153 cm square?
Letting x be the length of the rectangle and (x - 8) be the width of the rectangle,x(x - 8) = 153,subtracting 153 from each side, x2 - 8x - 153 = 0,solving for x, (x - 17)(x + 9) = 0, then x = 17 or x = -9,substituting 17 for x, the dimensions of the rectangle are 17cm and 9cm.
If the perimeter is 1213 cm find the length of each side?
All we can tell is length plus width is 606.5 ...(always assuming you're talking about a rectangle)
How do you figure out sg ft for rooms?
Multiply by length x the width of the room. Sometimes the room is not just a rectangle. Then you must divide it up into smaller pieces each of which is a rectangle.
Is length times width the answer to perimeter?
No. (a) it is perimeter, not perimeder (b) it is length, not lenght. Length times Width is area (for a rectangle). Perimeter is the sum of all the sides, so 2*(Length + Width)
