Answer:
Length of the side W = 9cm
Step-by-step explanation:
A square has all sides equal. So since one side is 9cm, the rest will be 9cm as well. The side marked as 'W' is 9cm.
You can find this in another way (if the length of the sides aren't given) :-
The area is 81
gives the area
Let's take the side as x.
So,
= Area
= 81
x =
x = 9cm.
So, each side of the square would be 9cm!

Step-by-step explanation:
I'll do the first problem as an example.
∠P and ∠H both have one mark. That means they're congruent.
∠T and ∠G both have two marks. So they're congruent.
∠W and ∠D both have three marks. So they're congruent.
So we can write a congruence statement:
ΔPTW ≅ ΔHGD
We can write more congruence statements by rearranging the letter, provided that corresponding pairs have the same position (P is in the same place as H, etc.). For example:
ΔWPT ≅ ΔDHG
ΔTWP ≅ ΔGDH
