Final answer:
The area of a triangle can be calculated using the formula (base x height) / 2. If the base is 4 yards and the height is 15 yards, the area is (4 x 15) / 2 yards². To convert yards to feet, multiply the number of yards by 3.
Step-by-step explanation:
The student appears to be asking for the area of a triangle with some given dimensions, although the complete details of the triangle are not provided in the question. Usually, the area of a triangle is determined by the formula Area = (base x height) / 2. For example, if one side of the triangle (the base) is 4 yards, and the perpendicular height from that base is 15 yards, the area would be (4 yards x 15 yards) / 2.
Using the provided conversion, where 1 yard equals 3 feet, one might convert measurements between feet and yards if needed. However, for calculating the area in yards², no conversion is necessary.
The question of how many feet are in a certain number of yards can be answered by multiplication. For instance, there are 4 yards x 3 feet/yard = 12 feet in 4 yards, as units of yard in the numerator and denominator cancel out.
