The sum means that Eric is 3.3 m above sea level.
<h3>What is an addition expression?</h3>
This is a way of taking the sum of two or more expressions.
Given the following parameters
- The distance while descending = -13.7 meters
- The distance while ascending = +15.2 meters
An additional expression in the form of Descent + Ascent to represent this situation will be -13.7 + 15+ 2
<u>Calculate the sum:</u>
Sum = -13.7 + 15+ 2Sum = 3.3 meters
Hence the sum means that Eric is 3.3 m above sea level.

Best estimate of the area of a triangle = 100
.
Solution:
Given base of the triangle = 23.62 cm
Height of the triangle = 8.33 cm
Area of the triangle = 


Area of the triangle = 98.3773 
Estimation means rounded off to the closest correct answer.
98.3773 rounded off to 100.
Hence, best estimate of the area of a triangle = 100
