Answer:
29.4 mm
Step-by-step explanation:
To determine the perimeter of a shape, we typically need more information than just the area. However, if we know the shape is a square, since all sides of a square are equal, we can use the area to find the length of one side, and then use that to calculate the perimeter.
The area of a square is given by the formula:
Area
=
side
2
Area=side
2
Given that the area is 54 mm, we can solve for the side length:
54
=
side
2
54=side
2
Taking the square root of both sides to solve for the side length:
side
=
54
side=
54
side
≈
7.35
mm
side≈7.35 mm
Now that we know the side length, we can find the perimeter of the square, which is the sum of all four sides:
Perimeter
=
4
×
side
Perimeter=4×side
Perimeter
=
4
×
7.35
Perimeter=4×7.35
Perimeter
≈
29.4
mm
Perimeter≈29.4 mm
So, if the area of the shape is 54 mm, and it's a square, the perimeter is approximately 29.4 mm.
