Area of Rectangles and Squares worksheet, Year 5 maths

Area of Rectangles and Squares: Year 5 maths

This topic covers finding the area of squares, rectangles, and compound rectilinear shapes. Students practise multiplying base by height, splitting composite shapes, and finding missing dimensions given area.

What this covers

Area of Rectangles and Squares is taught in Year 5 (age 9 to 10, KS2) as a main teaching focus. It sits in the Measurement strand.

Worked example

A rectangle has a length of 9 cm and an area of 54 cm^2. What is its width

Recall the formula for area: Area = length × width.
Substitute known values: 54 = 9 × width.
Divide area by length: width = 549 = 6 cm.

Answer: 6 cm

Area of rectangles and squares using integer multiplication within times tables.
Area of rectangles with two-digit integer dimensions or simple decimal lengths.
Area of compound rectilinear (L or T) shapes by partitioning into two rectangles.
Reverse problems finding unknown side lengths, or problems combining perimeter and area.

Common mistakes

Confusing area and perimeter by adding all side lengths instead of multiplying base by height.
Forgetting to subtract overlapping areas when partitioning compound rectilinear shapes.
