A garden is edged with landscaping tiles that are 9.2 cm wide. The length of the garden is 6.2 m and the width of the garden is 5.6 m. What is the perimeter of the garden inside the landscaping tiles, to the nearest tenth of a meter?

Answer 1

the width and length are both reduced by 9.2cm on each side, so the new perimeter is

2((6.2-2*.092)+(5.6-2*0.92)) = 19.552 m
