We know that angle C and angle A are congruent because this is a parallelogram. We also know that in a triangle, all the angles add up to 180.

Looking at triangle ABD (or ABY, depending on how you look at it), angle A is 63 degrees and angle B is 72 degrees. To find out angle y, we subtract 72 and 63 from 180.

180-72-63
=45

Therefore, angle y is 45 degrees.

I hope this helps!

Answer 
Left border = 8 feet
Lower border =32 feet
Area=128 〖ft〗^2

Explanation 
The area is a right triangle.
Let us take the left border to be y feet and the lower border to be x feet
Area=1/2 yx
The cost of fencing would be 4y+x=64.
From this expression x=64-4y
Substituting this value of x in the area we have;
Area=1/2 y(64-4y)
A=32y-2y^2
To get the maximum area of the triangle the first derivative of the area would te equal to zero.
A=32y-2y^2
dA/dy=32-4y=0
4y=32
y=8
Since x=64-4y
x=64-(4×8)=32
The dimensions of the garden are 8 feet by 32 feet.
Since the garden is a right triangle,
Area=1/2×8×32
Area=128 〖ft〗^2
