All triangles in this shape have same area as they have same base length and height length.
- area of triangle: 1/2 * base * height
Here the base is 4.2 cm and height is 2.5 cm for all the given triangles.
As a result, we can say that the area of 
A, B, C are equal.
now you must first distribute the 2 in the brackets. multiply 2 by h and (-29)
now combine "like terms" (-58) with (-58) and 2h with (-h)
now that h has no coefficient (no number in front) you can bring the -116 over to the other side to isolate the variable (h). remember when you bring a number over the equal sign the signs change so (-116) becomes 166.
now add the two terms together
the final result is 157
Based on the heights of the summits of Mt. McKinley and Mt. Kosciuszko, we find that Mt. McKinley is higher than Mt. Kosciuszko by 13,000 ft
<h3>What are the heights of Mt. Kosciuszko and Mt. McKinley?</h3>
Mt. McKinley is reputed to be the tallest mountain in the North American continent which makes sense considering it has a summit with the height of 20,310 feet.
Mt. Kosciuszko on the other hand, is not that tall and stands at a height of 7,310 ft and is located in Australia.
The difference between both summits is:
= 20,310 - 7,310
= 13,000 ft
