Answer: The height of wall is 10.5 feet.
Step-by-step explanation:
Since we have given that
Number of bricks to build = 1470
Length of wall = 20 feet
We need to find the height of wall.
As we know that
Bricklayer's formula is given by
[tex]N=7LH\\\\1470=7\times 20\times H\\\\1470=140\times H\\\\\dfrac{1470}{140}=H\\\\10.5\ ft=H[/tex]
Hence, the height of wall is 10.5 feet.
