Answer: y = 6
Step-by-step explanation:
A square's area can be done by using s^2, where s is y in this case.  Because there are 5 squares, the area of the figure is 5y^2.  Because the area is also 180cm, 5y^2=180.
Then divide both sides of the equation by 5 to get y^2 = 36.  Then square root both sides of the equation to get y = 6.

The measure of angle (m ∠A) is 136°
<h3>Vertical angles theorem</h3>
From the question, we are to find the measure of angle A
From the given information, we have that 
∠A and ∠B are vertical angles
Thus 
∠A = ∠B 
and 
Also, from the given information,
m ∠A=(2x+26)° 
and 
m ∠B= (3x−29)° 
∴ (2x+26)° = (3x−29)°
Now, solve for x 
2x + 26 = 3x - 29 
26 + 29 = 3x - 2x 
55 = x 
∴ x = 55
But measure of angle A is given by 
m ∠A=(2x+26)°
Put the value of x into the equation, 
m ∠A=(2(55)+26)°
m ∠A=(110+26)°
m ∠A = 136°
Hence, the measure of angle (m ∠A) is 136°
