Options

A. 180
B. 178
C. 174
D. 176

Answer

To find the maximum number of trees that can be planted 20 meters apart on both sides of a straight road that is 1760 meters long, we can follow these steps:

### Step 1: Calculate the number of trees on one side of the road.
To find out how many trees can be planted on one side of the road, we need to divide the length of the road by the distance between the trees and then add one for the first tree.

**Formula:**
Number of trees on one side = (Length of the road / Distance between trees) + 1

**Calculation:**
Length of the road = 1760 meters
Distance between trees = 20 meters

Number of trees on one side = (1760 / 20) + 1
= 88 + 1
= 89 trees

### Step 2: Calculate the total number of trees on both sides of the road.
Since the trees are planted on both sides of the road, we need to multiply the number of trees on one side by 2.

**Formula:**
Total number of trees = Number of trees on one side × 2

**Calculation:**
Total number of trees = 89 × 2
= 178 trees

### Final Answer:
The maximum number of trees that can be planted on both sides of the road is **178 trees**.
