Q. Japhet is making small rectangular tiles for a mosaic. Each tile has an area of 7cm2 and is 141cm wide. How long is each tile?□cm
Convert to Improper Fraction: Convert the mixed number for the width of the tile to an improper fraction.141cm = 1+41=44+41=45 cm
Use Area Formula: Use the area formula for a rectangle, which is Area=width×length. We know the area (7cm2) and the width (45cm), so we can solve for the length.
Rearrange for Length: Rearrange the area formula to solve for the length. Length=widthArea
Substitute Values: Substitute the known values into the formula.Length = 45cm7cm2
Perform Division: Perform the division to find the length.Length = 7cm2×(54cm)−1Length = 7cm2×54Length = 528Length = 5.6cm
