Based on the length and width of the rectangular lawn, and the percentage the man has mowed, the strip width would be 40.5 m.
<h3>what is the width of the strip mowed already?</h3>
first, find the area of the lawn:
= 100 x 200
= 20,000 ft²
the area mowed is:
= 40.5% x 20,000
= 8,100 ft²
the width is therefore:
= 8,100 / 200
= 40.5 m
