Answer:

29 m

Step-by-step explanation:

The dashes mean that the lines are equal in length, so from this we can determine that the area marked 441 m² is a square.  

Area of a square = x², where x is the length of 1 side.  

Therefore, x = √441 = 21 m

Now we have a right-angled triangle with two legs of 20 m and 21 m.  We need to find the hypotenuse (labelled ?).  To do this, use Pythagoras' Theorem a² + b² = c², where a and b are the legs and c is the hypotenuse.

Therefore,

    20² + 21² = c²

⇒ 400 + 441 = c²

⇒            841 = c²

⇒               c = √841

⇒               c = 29

So the side marked ? on the diagram is 29
