KS2 Primary Maths Age 13-17 - Measure: Perimeters and Areas - Explained

The video tutorial explains how to calculate the length of a rectangle using identical right-angled triangles. It begins by introducing the concept of identical triangles and the given measurements. The tutorial then demonstrates how to find the base and height of these triangles, using the information that one side of the rectangle is 7 centimeters. By calculating the base as 3.5 centimeters and the height as 7 centimeters, the total length of the rectangle is determined to be 10.5 centimeters. The tutorial emphasizes the importance of understanding the problem setup and using given measurements effectively.
