Question

A rectangle hall has semicircular ends on the breadth wise sides. If the dimension of the rectangular portion are 12 m and 7m respectively. calculate the area of the hall. ​

Answer 1

Answer:

area=84

Step-by-step explanation:

length ×breadth = 12×7 =84

Answer 2

Answer:

length = 12 m

breadth = 7 m and it also diameter of semi circle

area of rectangle = l × b

= 12×7 = 84 m^2

area of two semicircle = 2( π r^2 )

= 2( 22/7 × 7/2 × 7/2 )

= 77 m^2

total are = area of rectangle + area of semi circle

= 84 + 77

= 161 m^2
