Top Answer

Use the following formulae:

Area = length x width

Perimeter = 2 x length plus 2 x width, or length + length + width + width

find the perimeter and area of a rectangle that is 15cm long and 5cm wide

The length of a rectangle is twice its width. If the perimeter of the rectangle is , find its area.

To find the perimeter you add and to find the area we multiply.

the length of a rectangle is 5 more then the width. Find the perimeter and the area of the rectangle

how do you find the area of a rectangle witha perimeter of 36 in You don't. You need more information For example a 1 x 17 rectangle has a perimeter of 36 and its area is 17. But a 2 x 16 rectangle also has a perimeter of 36 and its area is 32.

Rem to Find area and rectangle of a rectangle Input "Length?",l Input"Breadth?",b let area=l*b let perimeter=2*l+b ?area ?perimeter

You cannot.

you need length and width length multiply width = area length + length + width + width = perimeter

There is no relationship between the perimeter and area of a rectangle. Knowing the perimeter, it's not possible to find the area. If you pick a number for the perimeter, there are an infinite number of rectangles with different areas that all have that perimeter. Knowing the area, it's not possible to find the perimeter. If you pick a number for the area, there are an infinite number of rectangles with different perimeters that all have that area.

nope

Let's take a look at this problem.Rectangle Perimeter = 2(l + w)Rectangle Perimeter =? 2(2l + 2w)Rectangle Perimeter =? (2)(2)(l + w)2(Rectangle Perimeter) = 2[2(l + w)]Thus, we can say that the perimeter of a rectangle is doubled when its dimensions are doubled.Rectangle Area = lwRectangle Area =? (2l)(2w)Rectangle Area =? 4lw4(Rectangle Area) = 4lwThus, we can say that the area of a rectangle is quadruplicated when its dimensions are doubled.

You can find the perimeter of a rectangle if you know its area and the length of one side. Divide the area by the length of the known side and the quotient will be the length of a side perpendicular to the known side, and then multiply the sum of the two sides by two to find the perimeter.

the area of a rectangleis 100 square inches. The perimeter of the rectangle is 40 inches. A second rectangle has the same area but a different perimeter. Is the secind rectangle a square? Explain why or why not.

Perimeter: Add the length of the four sides. Area: Multiply length x width.

No. For example, a 4x1 rectangle will have an area of 4 and a perimeter of 10. A 2x2 rectangle will have the same area of 4, but a perimeter of 8.

You add all the sides up.

The perimeter of the rectangle is the sum of its 4 sides.

98 square feet

for area you multiply length times width and for perimeter you add all of the sides together

Yes, the perimeter or area of a rectangle can be an irrational number. Thanks

No,for example, a 1x2 rectangle has an area of 2 but a perimeter of 6

156 It is impossible to calculate the area of a rectangle from its perimeter if no other dimension is known. The area of a rectangle is the product of its length and width, and the perimeter is twice the sum of its length and width.

yes

There is no reason for the perimeter of a triangle to have any relation to the perimeter of an unrelated rectangle!

The perimeter of rectangle A would then be 80 because 80 to 100 is 4 to 5 simplified and the area of triangle A would depend on the sides and area of rectangle B which have not been given.
