Answer:
The base length of the triangle is 15 units
Explanation:
The area of a triangle is given by the formula; 1/2 *base* perpendicular height. In the presented scenario, we can determine the base by solving for base in the given equation; 1/2 *base*7 =52.5. Multiply both sides by 2 yields; base*7 =105. Dividing by 7 yields; base=15 units
