Question

A rectangular field is 90 yards wide and 140 yards long. give the length and width of another rectangular field that has the same perimeter but a larger area

Answer 1

Perimeter of rectangle is 2W + 2L
area of rectangle is WL

perimeter of 90 yards by 140 yards
...90×2 + 140×2 = 180+280 = 460 yards

area of 90 yards by 140 yards
....90×140= 12,600 square yards

Same size perimeter but larger area
100 yards wide by 130 yards long
100×2 + 130×2= 200+260 = 460 yards

area of 100 yards by 130 yards
100×130 = 13,000 square yards
