Question

A trees falls down. Its height 5cm. Top touches the ground.12cm.find the actual height of the tree?

Answer 1

Tree is broken at height = 5cm
Top touches the ground at height (H) = 12cm

H² = P² + B²

( Using Pythagoras property )

H² = (5cm)² + (12cm)²

H² = 25cm² + 144cm²

H² = 169cm²

H × H = 13 × 13 × cm × cm
H = 13cm

Original height = 13 + 5 = 18cm
