Question

part a
to find the area of \\( \triangle a b c \\), find the lengths of base \\( b c \\) and height \\( a b \\).

Explanation:

Step1: Determine the base \( BC\)

From the diagram, we can directly observe that the length of \( BC\) is given as \( 55\) feet.

Step2: Determine the height \( AB\)

The total vertical length from \( P\) to \( O\) is \( 35 + 20=55\) feet. Since \( AB\) is parallel to \( PO\) (assuming the figure is constructed in a standard way for calculating the area of \(\triangle ABC\) with \( BC\) as the base), the height \( AB = 55\) feet.

Answer:

Base \( BC = 55\) feet, height \( AB=55\) feet
