Area of Rectangles: planter boxes

For maths this week we were learning how to measure the area of the planter boxes.

Step 1: Cut the shape into 2 rectangles

Step 2: Calculate the area of each individual rectangle

Step 3:  Add the 2 areas together

In the example above, the area of the first rectangle was 12cm2 and the area of the second rectangle was 6cm2.

So the equation was 12cm2 + 6cm2 = 18cm2

So the area of the planter box is 18cm2.
