The 3 digit numbers when divided by 6 leaves remainder 1 are
103, 109.......997
where a=103, d= 109-103=6 and An= 997
An= a+(n-1)d
997=103+(n-1)×6
(n-1)6=997-103=894
n-1=894/6=149
n=149+1=150
so, there are 150 numbers

Yogita Ingle 6 years, 1 month ago

Height of the sq. room = 4m

Area of 4 walls = 80 sq. m

perimeter × height = 80

4 × side × 4 = 80

side × 16 = 80

side = 80/16

= 5 m

Now ,

Area of its floor = (side)²

= (5)²

= 25 sq. m

Hence, The area of the floor of the sq. room is 25 sq m .
