Identical squares of side one unit contain some circles shaded blue. In which of the four examples is the shaded area greatest?

Can you maximise the area available to a grazing goat?

Find a cuboid (with edges of integer values) that has a surface area of exactly 100 square units. Is there more than one? Can you find them all?

If you move the tiles around, can you make squares with different coloured edges?

What is the greatest volume you can get for a rectangular (cuboid) parcel if the maximum combined length and girth are 2 metres?

If you have only 40 metres of fencing available, what is the maximum area of land you can fence off?

Use a single sheet of A4 paper and make a cylinder having the greatest possible volume. The cylinder must be closed off by a circle at each end.

Draw some isosceles triangles with an area of $9$cm$^2$ and a vertex at (20,20). If all the vertices must have whole number coordinates, how many is it possible to draw?

An aluminium can contains 330 ml of cola. If the can's diameter is 6 cm what is the can's height?

Can you find rectangles where the value of the area is the same as the value of the perimeter?

What's the largest volume of box you can make from a square of paper?

How can you change the area of a shape but keep its perimeter the same? How can you change the perimeter but keep the area the same?

How can you change the surface area of a cuboid but keep its volume the same? How can you change the volume but keep the surface area the same?

I'm thinking of a rectangle with an area of 24. What could its perimeter be?

What are the possible areas of triangles drawn in a square?

Can you deduce the perimeters of the shapes from the information given?

A colourful cube is made from little red and yellow cubes. But can you work out how many of each?

We usually use squares to measure area, but what if we use triangles instead?

Isometric Areas explored areas of parallelograms in triangular units. Here we explore areas of triangles...
