Question

Alexandra wishes to surround his rectangular flower bed with a gravel walk 1 meter wide flower bed is 5m and the width is 4m. What will be the area of the gravel walk?

Answer 1

Answer : 8

Explanation: If the area of the rectangle is 5x4 and the gravel walk would be 1 meter on each side you subtract 5-1 and 4-3 to get the 4x3. This is now the inside area or where the flowers are. Now multiply 5x4 (20) to find the total area of the flower bed and 4x3 (12) to find the inside area where the gravel is not. Subtract these (20-12) to find the area of the gravel (8). :)
Hope this helps
