Perimeter and Area
- The perimeter of a shape is the distance around the outside of it – it would be measured in distance such as millimetres, centimetres, metres or kilometres.
- The easiest way to find perimeter is to choose a point, then travel around the shape adding on the lengths of each side.
If we start from the corner marked with an X and move clockwise, this would be the sum – 11+6.5+8+4 = 29.5cm
3. The area of a shape is the amount of space covered inside the shape. It can be measured in units such as mm2 , cm2
4. The area of a rectangle is found by multiplying the length by the width.
We can find the area of the shape by multiplying the length, 7cm, by the width, 5cm.
7 x 5 = 35 therefore, the area is 35cm 2
1) Which two shapes have the same perimeter?
Draw two shapes on this on this grid. Both of them should have an area of 10 squares.
4) Abid has made a new shape out of two triangles.
5) What is area of the shape on the grid?
