Answer:

Given:
Length of the rectangle = 4 yd longer than its width
Perimeter of the rectangle = 36 yd
To Find:
Area of the rectangle
Step-by-step explanation:
Let the width of the rectangle be 'w' yd
So,
Length of the rectangle = (w + 4) yd

So,
Width of the rectangle = 7 yd
Length of the rectangle = (7 + 4) yd
= 13 yd

you would use sine
sine = opposite side / hypotenuse
and solve for opposite side (x)
so sine of 70*14= which is about 13.146
