A composite rectilinear shape is a composite shape made from rectangles.

Area of composite rectilinear shapes

Maths

In this unit pupils learn how to derive and use the formula for the area of a triangle and trapezium. In the future unit, this knowledge is called upon to find the volume of different prisms and area of composite shapes

In this unit, pupils explored the relationship between perimeter and area. In particular, they considered whether a shape can have the same area and perimeter value

Perimeter and area

Calculate the area of this compound rectilinear shape (you do not need to state the units).

Determine whether you can calculate the area of this shape given the information provided in the diagram.

What is the length of the line marked $$b$$?

A composite {{}} shape is made from rectangles.

What is the length of the side marked $$a$$ in the diagram? 

What is the length of the side marked $$b$$ in the diagram?

Calculate the area of the rectangle (you do not need to state the units).

Calculate the area of the rectangle with a base of 11 m and a height of 7 m (you do not need to write the units).

This lesson will soon be taken down.
