Question

The crane moves on two caterpillar tracks, each with a contact area with the ground of 3.4m². Calculate the total area the crane has with the ground.

a) 6.8m²

b) 10.2m²

c) 13.6m²

d) 17.0m²

Answer 1

The total area that the crane has with the ground is 6.8 m².

Step-by-step explanation:

The total area that the crane has with the ground is the sum of the contact areas of the two caterpillar tracks. Given that each track has a contact area of 3.4 m², the total area is 3.4 m² + 3.4 m² = 6.8 m².
