The area of rectangle is : 32.0
What else can I help you with?
A rectangle is 4cm longer than it is wide what are the demesions if the area is 8cm?
Area of a rectangle = length x width If length = L and width = W, then Area = L x W For this case, the length is 4 cm longer than the width. Therefore, L = W + 4cm Replace length in the area equation at the top with this new L value: Area = (W + 4cm) x W Area = W^2 + (4cm) x W And area is 8 cm^2 (I assume you meant to say 8cm^2 is the area) Then: 8cm^2 = W^2 +4W This is a quadratic equation (because of the w^2 value), if you solve for W using the quadratic formula (Google it), you get W = 1.464cm Therefore, the length L = W + 4cm = 1.464cm + 4cm = 5.464cm Dimensions are L = 5.464cm and W = 1.464cm

What is the area of a right triangle that is 4cm by 8cm?
The area of a right-angle triangle is half of the area of a rectangle 8cm x 4cm. Find the rectangle area and divide by half to find the area of the right-angle triangle. Therefore: 8 x 4 / 2 = 16cm2 * * * * * The above answer assumes that the two given lengths are the shorter legs of the triangle. It is, however, possible that these are the hypotenuse and one leg. In that case, the second leg is 4*sqrt(2) cm and the area of the triangle is 4 * 4*sqrt(2) / 2 = 8*sqrt(2) = 11.31 cm2.
What is the area of a rectangle that is 11cm long and 8cm wide?

What is the dimensions of a rectangle has 20 cm area and 18 cm perimeter?
4cm x 5cm
You a rectangle has an area of 40 square cm and has a length of 8 cm and another rectangle is one-half the size of the other rectangle what is the width of the rectangle that is one-half the area of?
the first rectangle is 8cm x 5cm the second rectangle has an area of half of 40 = 20 sq cm it could be 4cm x 5cm or 8cm x2.5cm or 10cm x 2cm or any pair of numbers whose product is 20 if you wanted the rectangles to be congruent ie have the same ratio of length to width then you need to employ irrational numbers the answer in this case is 8 divided by sqrt(2) for length and 5 divided by sqrt(2) for width or approximately 5.6568542494923801952067548968388cm x 3.5355339059327376220042218105242 cm
What is the area of 6 cm x 4cm?
6 cm x 4 cm = 24cm2 (length x width = area)
A rectangle paper with length 8cm is folded into half and the ratio of its length to its width remains unchanged If the square of the width of the original piece of paper is xcm2 Find the volume of x?
Well, darling, if the length of the rectangle paper is 8cm and it's folded in half, that means the width is now 8cm as well. Since the ratio of length to width remains the same, the original width must have been 4cm. So, the square of the original width (4cm) is 16cm^2. Therefore, the volume of x is 16 cubic centimeters. Voilà!
How do you name area?
Here is how you name it:Example: The length of a rectangle is 4cm and its height is 2cm. The area of it would be 4cm x 2cm= 8cm. You would name it like this: 8cm2 You would name it like this since it is a 2-dimensional figure, If you need to find the volume of a 3-dimensional figure you would put an"exponent" of 3 instead of two since it is 3-dimensional. Example: The base of a rectangular prism is 5cm, the width of it is 4cm, and its height is 2cm. To find the volume you would do, 5cm x 4cm x 2cm= 40cm. You would name it like this: 40cm2Hope this Helps!:)
Is it possible that a square can have the same perimeter and area?
Yes (apart from units):If the side of a square is 4cm then itsperimeter is 4cm + 4cm + 4cm + 4cm = 4 x 4cm = 16cm;area is 4cm x 4cm = 16cm2
What is the perimeter of a rectangle 7cm x 4cm?
22 cm
Area of 3 centimeters and 8 centimeters?
Assuming the shape is a 3cm x 8cm rectangle, the area of this shape will be 3 x 8 = 24 cm2 - or 24 square centimetres.
