A rectangular field has dimensions 25 m by 15 m. Two mutually perpendicular passages, 2 m wide have been left in its central part and grass has been grown in rest of the field. The area (in sq. metres) under the grass is :
Answer & Solution
Correct Answer:
Option
B
Area of the field :
= (25 × 15) m2
= 375 m2
Area of the passages :
= (25 × 2 + 15 × 2 - 2 × 2) m2
= 76 m2
Area under grass :
= (375 - 76) m2
= 299 m2
= (25 × 15) m2
= 375 m2
Area of the passages :
= (25 × 2 + 15 × 2 - 2 × 2) m2
= 76 m2
Area under grass :
= (375 - 76) m2
= 299 m2
