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
