Curriculum subtopic:   Calculate Areas

Popular topics:   Area worksheets, Shape worksheets

Difficulty level:   #### Worksheet Overview

The basic unit of area is a centimetre square. Example 1

Calculate the area of this shape, made of centimetre squares and half squares. There are 10 full squares and 2 half squares.

Area = 10 × 1 + 2 × 0.5 = 10 + 1 = 11 cm2

Example 2

Calculate the area of this shape, made of centimetre squares and half squares. The area of a rectangle = length × width

Area of rectangle = 3 × 2 = 6 cm2

Area of triangle, which is half a square = 0.5 cm2

Area of shape = 6 + 0.5 = 6.5 cm2
