**Answer:**

b2 = 1

**Step-by-step explanation:**

A = h(b1 + b2)

Given:

A = 16

h = 4

b1 = 3

b2 = x

Work:

A = h(b1 + b2)

16 = 4(3 + x)

16 = 12 + 4x

4x = 16 - 12

4x = 4

x = 1

The height in feet of the tree is **111.5 ft. **

<h3>How to find the height of a tree?</h3>

The** height** of a house is 52 ft.

A tree beside the house is 7.5 ft more than twice as tall.

The height of the tree is as follows:

let

**x = height of the house**

Therefore,

The height of the house = x = 52 ft

Hence,

**height of the tree = 7.5 + 2x**

height of the tree = 7.5 + 2(52)

height of the tree = 7.5 + 104

height of the tree = 111.5

**height of the tree = 111.5 ft**
