Answer:
A square with an area of 49 square inches has a perimeter of 28 inches.
Step-by-step explanation:
The square root of 49, or 7 inches, is then the length of one side. The formula for the perimeter of a square is the sum of all sides. Since all sides are 7 inches, the perimeter is 7 + 7 + 7 + 7, or 28 inches. The area of the square is reported in square inches because inches are multiplied by inches to yield square inches.
Area = L x W
So 49= L x W.
Length and width have to be the same as a square so length and width are 7inches. Therefore the perimeter is 2(L+W)
So 2(7+7)
2 x 14 = 28 inches
So 49= L x W.
Length and width have to be the same as a square so length and width are 7inches. Therefore the perimeter is 2(L+W)
So 2(7+7)
2 x 14 = 28 inches
