 # Calculate the Area of Rectangles Using Squares

In this worksheet, students will be asked to find the area of rectangles using squares and standard units, square centimetres and square metres. Key stage:  KS 2

Curriculum topic:   Measurement

Curriculum subtopic:   Calculate/Estimate Areas

Difficulty level:   ### QUESTION 1 of 10

The area of a 2D shape refers to the amount of space it takes up.

The area of a shape is measured in square units, either cm² or m².

In this activity, you will be asked to find the area of different rectangles by counting the number of 1 cm² the rectangle occupies.

e.g. Look carefully at the rectangle below.

Find its area by counting the number of squares it covers. Area = 28 cm²
