Answer:
80 yards
Step-by-step explanation:
Using the area formula, A = lw, set up an equation where w represents the width.
The length can be represented by 3w because it is 3 times the width:
A = lw
300 = (3w)(w)
300 = 3w²
Solve for w:
300 = 3w²
100 = w²
10 = w
So, the width is 10 yards.
The length will be 30 yards since the length is 3 times the width.
Then, add the lengths and widths together to find the perimeter:
10 + 10 + 30 + 30
= 80
So, the perimeter is 80 yards
