Answer me urgent fast ​

Answer 1

Step-by-step explanation:

Remaing part=24 feet.

3/7 of 24 feet=3/7×24=10.29 feet

Remaining part after 2nd month=height of building in 3rd month + work remaining

=10.29+24=34.29 feet

Remaining part also equals to

7/12

because 5/12+7/12=12/12=1.

Let common multiple be x.

Here 12x= complete height of building.

we know

7x=34.29

x=34.29/7=4.9(approx)

12x=4.9×12=58.8 feet

The total length of building is 58.8 feet.
