DIRECTIONS: Passage ? 2 Read the passage(s) given below and answer the questions that follow A rectangular park is of dimensions 90 m by 80 m. Four paths pass through the park such that two paths each of width 2m are parallel to the breadth and two paths each of width 3 m are parallel to the length. Total area of the two roads along the length is

A)  \[270\,{{m}^{2}}\]             

B)  \[810\,{{m}^{2}}\]

C)  \[540\,{{m}^{2}}\]          

D)  \[504\,{{m}^{2}}\]

Correct Answer: C

Solution :

    Length of the road = 90 m Breadth of the road = 3 m Area of the road \[=90\times 3=270\,{{m}^{2}}\] \[\therefore \]  Total area of the two roads along the length \[=2\times 270=540\,{{m}^{2}}.\]
