Question

a rectangular lawn measures 30 m by 40 m. jason is cutting the lawn from the outside perimeter in toward the centre by cutting strips along the entire perimeter first, then continuing as he cuts toward the centre. how wide is the strip that has been cut along the outside when the area is half cut?

Answer 1

The width of the strip that has been cut along the outside when the area is half cut is 20 m.

Step-by-step explanation:

To find the width of the strip that has been cut along the outside when the area is half cut, we need to find the area of the rectangle and divide it by 2. The area of a rectangle is found by multiplying its length by its width. In this case, the length is 30 m and the width is 40 m, so the area is 30 m × 40 m = 1200 m2. When the area is half cut, the remaining area will be 1200 m2 ÷ 2 = 600 m2.

To find the width of the strip, we can divide the remaining area by the length of the rectangle. The remaining area is 600 m2 and the length is 30 m, so the width of the strip is 600 m2 ÷ 30 m = 20 m.
