A rectangular field is 30 m by 20 m. A farmer wants to plant trees along the perimeter with equal spacing. If he plants a tree at each corner and the distance between trees is 5 m, how many trees does he plant?
- A.18 trees
- B.20 trees
- C.22 trees
- D.24 trees
Kunci jawaban & pembahasan
Jawaban: 20 trees
Perimeter = 2(30+20) = 100 m. Number of intervals = 100 ÷ 5 = 20. Since it's a closed loop, number of trees = number of intervals = 20 trees.
