<h2>Step-by-step explanation:</h2>When we say a is no more than b, we express this in a mathematical language as follows:
In this inequality, we know that the area of the triangle is no more than 168 in². In other words, if the area is named , then:
We also know that the height of a triangle is 4 inches greater than twice its base. Translating this in a mathematical language:
From geometry, we know that the area of a triangle is given by:
Matching (1), (2) and (3):
Since the length of the base of the triangle is , then
Finally, correct option is B.
