The curved surface area of a cylinder with a height of 8cm and diameter of 10cm is 251.33cm2
8cm * 8cm = 8*8 cm2 = 64 cm2
It is a rectangle.
A = 5.093 cm2
A square of perimeter 32cm has 4 sides of length 8cm. Area = Side1*Side2 Area = 8cm*8cm Area=64cm2
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.
the area of a 2D shape with dimensions 8cm and 12cm is 96cm2, but if you're talking about surface area of a 3D shape then you need the other dimension.
32 cm² = 8cm²/2
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
The lengths of the sides of any shape, other than a triangle or regular polygon do not provide enough information to calculate the area. In the same way that a square can be flexed into a rhombus and the rhombus can then be flattened so that its area changes, the information given in the question is not adequate.
The area of triangle is : 24.0
