Question

A rectangular hall 18m long and 15m broad is surrounded by a verandah, 2m wide. Find the area of the verandah.

Answer 1

Answer:

Area of verandah is 148 m²

Step-by-step explanation:

Length of rectangular hall = 18 m

Breadth of the rectangular hall = 15 m

Additional length of the verandah = 2 x 2 = 4 m

Additional breadth of the verandah = 2 x 2 = 4 m

Area of verandah = Area of verandah including the hall - Area of rectangular hall

= (18+4)(15+4) - (18x15) m²

= (20x17) - 270 m²

= 418 - 270 m²

= 148 m²
