Answer:
56 feet
Explanation:
So the area of a quadrilateral is, length * width
but since the, length = width, in a square then we can say that the area of a square is, length ^ 2, or, width^ 2
so we can say that
length ^ 2 = 196
the sqrt of 196 is 14 so
length = 14
Since there are four sides to a square, we need to multiply the length by 4 to find the total material needed
14 * 4
= 56
