hello!
so area of a square is calculated by this equation
s^2 = a
which means if you multiply two sides together you get the area
what you want to do now is to find a side of the square
plug in the 900 square meters
s^2 = 900
square root both sides to isoate the variable
s = 30 meters
this means that one side is 30 meters
since it is a SQUARE all four sides are equal
just multiply 30 by 4 and that will get the amount of fencing you'll need
30*4 = 1200 meters
you will need 1200 meters of fencing
WAIT
there is a possibility that one side of the house has already enclosed one side of the fence
so if that's the deal then
30*3 = 900meters
IF ONE SIDE OF THE HOUSE IS ALREADY ENLCOSING ONCE SIDE THEN YOU WILL NEED 900 meters of fencing.
X=12 I believe because 4x3x1=12
∠ABC = 101°(given) so y + x = 101°: 25° + x = 180° → x = 76°
p & w are alternate interior angles so are congruent: w = p = 27°
y & z are alternate interior angles so are congruent: z = y = 25°
z, w, E is a triangle so sum is equal to 180°: 25° + 27° + E = 180°→ E = 126°
E & e are supplementary so sum is equal to 180°: 126° + e = 180°→ e = 54°
x, e, n is a triangle so sum is equal to 180°: 76° + 54° + n = 180°→ n = 50°
Answer: n=50°, w=27°, x=76°, z=25°
