Calculating the area of rectangles using length × width, with answers in square units (cm², m²).
Where your child meets this in real life: Working out how much carpet is needed for a room or paint for a wall
SEAGReady breaks area of rectangles into 3 steps, taught in order so each skill builds on the last.
Calculate the area of rectangles with single-digit dimensions using length x width, giving answer in square units
Calculate area when one or both dimensions are two-digit numbers
Extract dimensions from real-world contexts and calculate rectangular area
Three free sample questions from our area of rectangles course. Every question comes with a full explanation, and hints that guide without giving the answer away.
Sean is covering a small photo frame with paper. The frame is 5 cm long and 3 cm wide. What is the area of the frame?
Answer: B. 15 cm²
The frame is 5 cm long and 3 cm wide. Area = length × width Area = 5 × 3 = 15 cm² The area of the frame is 15 cm².
Stuck? Start here: Area measures the space inside a rectangle. What operation do you use?
A rectangular poster is 12 cm long and 5 cm wide. What is its area?
Answer: D. 60 cm²
The poster is 12 cm long and 5 cm wide. Area = length × width Area = 12 × 5 Using partitioning: 12 × 5 = (10 × 5) + (2 × 5) = 50 + 10 = 60 cm² The area of the poster is 60 cm².
Stuck? Start here: Area = length × width. What is 12 × 5?
Ben's dad is buying tiles for the kitchen floor. The floor is 4 metres long and 3 metres wide. How many square metres of tiles does he need?
Answer: B. 12 m²
The floor is 4 metres long and 3 metres wide. Area = length × width Area = 4 × 3 = 12 m² Ben's dad needs 12 square metres of tiles.
Stuck? Start here: Look for the words that tell you the dimensions: 'long' and 'wide'.
This is the exact interactive worked example your child sees in SEAGReady. Step through it and watch the method build up.
Niamh is covering a small notice board with fabric. The board is 6 cm long and 4 cm wide.
What is the area of the notice board?
6 cm × 4 cm
Step 1 of 4
Niamh is covering a small notice board with fabric. The board is 6 cm long and 4 cm wide.
What is the area of the notice board?
The area of the notice board is 24 cm².
The key insight: Area counts the squares inside - multiplication is a quick way to count rows!
Watch out: 6 + 4 + 6 + 4 = 20 cm. Adding the sides gives perimeter (distance around), not area (space inside).
These are the misconceptions we see most often in area of rectangles, including the ones our practice questions are specifically designed to catch.
Struggling with area of rectangles? The real gap is often in one of these earlier topics.
SEAGReady finds the exact step where your child gets stuck, teaches it with worked examples like the one above, and brings it back for review so it sticks.
