What size in inches is a 16cm x 13 cm?
A 16cm x 13cm rectangle is approximately 6.3 inches x 5.1 inches.
The length of a rectangle is 4cm longer than the width if the perimeter of the rectangle is 20cm what is the area of the rectangle?
First find the dimensions of the rectangle. Let the length be x+4 and the width be x: 2(x+4+x) = 20 2x+8+2x = 20 4x = 20-8 4x = 12 => x = 3 Therefore: length = 7cm and the width = 3cm Area = length*width => 21cm2
What are three shapes that have a perimeter of 12 cm?
Square side 3cm. Rectangle 2cm x 4cm. Equilateral triangle side 4cm.
What is the equation for the area is the length of a side squared?
to work out the area of a sqaure it is the length of the side multiplied by another side. seing as the sides of a sqaure are all equal, is is the side of a square multiplied by itself. for example if the side of a square was 4cm the equation would be: 4cm x 4cm = 16cm^2 do not get this equation confused with the equation for a rectangle which is length multiplied by the width. (L x W)
A cube measures 4cm x 4cm on a side what is the surface area?
96 cm.^2
What is the area of a rectangle which is 4cm x 8cm?
The area of rectangle is : 32.0
What is the area of 6 cm x 4cm?
6 cm x 4 cm = 24cm2 (length x width = area)
What is the dimensions of a rectangle has 20 cm area and 18 cm perimeter?
4cm x 5cm
What size in inches is a 16cm x 13 cm?
A 16cm x 13cm rectangle is approximately 6.3 inches x 5.1 inches.
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
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
A rectangle with the area of 24cm2 and the width is 6 what is the length?
If 2 sides of the rectangle are 6cm, then the remaining 2 sides are 4cm. Area = Length x Breadth Breadth = Area / Lenghth 24 = 6 x Breadth Breadth = 24 / 6 = 4
What is perimeter and area called in mathematics?
The perimeter is the addition of the all the sides of the shape. For example if a rectangle has two sides which are 4cm and two sides which are 7cm, then the perimeter will be 4cm+4cm+7cm+7cm. The perimeter would therefore be 22cm. The area of a shape is gotten by multiplying the length and breadth of the shape. For example, in a rectangle witrh the same measurements above, the area will be 4cm x 7cm and that would 28cm. You have to use the square sign but I can't do that here.
When the dimensions of a 2Cm X 5Cm rectangle were increased by equal amounts the area was increased by 18cm find the dimensions of the new rectangle using factoring?
The new dimensions are 4cm and 7cm
The length of a rectangle is 4cm longer than the width if the perimeter of the rectangle is 20cm what is the area of the rectangle?
First find the dimensions of the rectangle. Let the length be x+4 and the width be x: 2(x+4+x) = 20 2x+8+2x = 20 4x = 20-8 4x = 12 => x = 3 Therefore: length = 7cm and the width = 3cm Area = length*width => 21cm2
What are three shapes that have a perimeter of 12 cm?
Square side 3cm. Rectangle 2cm x 4cm. Equilateral triangle side 4cm.
