Answer 1

WE WILL COMBINELY FIND AREA OF LAB A, B,AND C

AREA OF A+B+C = AREA OF RECTANGLE

=> 60*20

=> 1200 m²

AREA OF CIRCLE = 2πr

=> 2*3.142*10

=>62.84 m²

TOTAL AREA OCCUPIED BY LABS = 1200 + 62.84

=> 1262.84 m²

TOTAL AREA = 100*80

=> 8000 m²

PERCENTAGE :-

1262.84 * 100/8000

=> 15.7855% ~ 15.8%
