Question

I will mark as BRAINLIEST​

Answer 1

Answer:

14)2:12 p.m.

15)7,800 m

Step-by-step explanation:

14)The timings of the flickering of each light:

1st light = 8

2nd light = 18

3 rd light = 24

we need to find the lcm.

LCM= 2*2*2*3*3=72

They will flicker again together after  

1 :00 + 72 min.

= 2:12 p.m.

∴ The light will again together at 2:12 p.m.

15) In this question we need to find the area of the function hall.

Dimensions of Function hall:

length = 260 m

width/breadth = 120 m

we can understand that this is a rectangular function hall.

Area of rectangle = l*b

= 260 m * 120 m

= 31,200 m²

so now we need to find the side of this area.

31,200 m² / 4

= 7,800 m²

∴ The side is 7,800 m

hope this helps.
