Question

The average height of 3 apartment blocks is 145.6 m the height of block A is 128.7 m and the height of block C is 138.9 m what is the height of block B?

Answer 1

`H_B=169.2m`

Explanation:

From the question we are told that:

Average height of blocks
`H_(ABC)=145.6`

Height of block A
`H_A=128.7`

Height of block C
`H_C=138.9`

Generally the equation for Height of block C is mathematically given by

Since

`H_(ABC)=(H_A+H_B+H_C)/(3)`

Therefore

`H_B=(H_(ABC)*3)-(H_A+H_B)`

`H_B=(145.6*3)-(128.7+138.9)`

`H_B=169.2m`
