mrs gardner is paving the sidewalk in front of her home with square tiles. the perimeter of each tile is 40 inches. which pair of equations can be used to find the area of each tile in square inches
The perimeter of SQUARE tile is 40 inches. Since the shape is a square and a square has 4 sides, 40 divided by 4 is 10. Each side is 10 inches. The area's formula is length times width, so 10×10=100. The square tile is 100 inches squared.
