Complementary angles their sin and cos equal
Thus,
x+x=90
2x=90
x=45 degrees
length = 8 yd and width = 2 yd
So, Option D is correct.
Step-by-step explanation:
Area of rectangular playground = 16 square yards
Width of playground = w
Length of playground = l = 4w
We need to find length(l) and width(w)
The formula used is:

Putting values:

Since width of rectangle is always positive, so we will take w = 2
So. Width = 2
Length = 4w = 4(2) = 8
Hence, length = 8 yd and width = 2 yd
So, Option D is correct.
