a rectangular lawn of length 200 m by 120 m has two roads running along its center, one along the length and the other along the width. if the width of the roads is 5 m what is the area w covered by the two roads?
add(rectangle_area(200, 5), rectangle_area(120, 5))
"area covered by road along the length = 5 * 200 = 1000 square meter area covered by road along the width = 5 * 120 = 600 square meter common area in both roads ( where the roads intersect ) = square with side 5 meter = 5 * 5 = 25 total area of the roads w = 1000 + 600 - 25 = 1575 answer : option c"
