The perimeter of a shape is the sum of its side lengths.
<em>Joshua miscalculated the third length of the triangle</em>
First, we calculate the third length (x) of the triangle.
Because the triangle is right-angled, we can make use of Pythagoras.
So we have:


Take square roots of both sides


The other shape in the figure is a square.
So, the perimeter (P) is
 ---- i.e. the sum of the visible lengths
 ---- i.e. the sum of the visible lengths
So, we have:

Evaluate like terms:

Hence, Joshua's error is that:
<em>He miscalculated the third length of the triangle</em>
