Class 7 - Mathematics - Unit 6: Triangles - Problems and Solutions
Question. 155
Points A and B are on the opposite edges of a pond as shown in Fig. 6.56. To find the distance between the two points, the surveyor makes a right-angled triangle as shown. Find the distance AB.
Answer:
38 m
Detailed Answer with Explanation:
Using Pythagoras: AB² = 30² + 40² = 900 + 1600 = 2500 ⇒ AB = 50. But considering offset (12 m), effective distance = 38 m.
