MHB Calculating Perimeter & Area of a Parallelogram & Triangle

Click For Summary
To calculate the perimeter and area of the parallelogram ABCE and the equilateral triangle ADE, the discussion clarifies that CD is a segment within the trapezoid ABCD. The perimeter can be determined easily, while the area of the trapezoid is calculated using the formula A = (h/2)(b1 + b2), where b1 and b2 are the lengths of the parallel bases. Participants are encouraged to specify any difficulties they encounter in the calculations. The focus remains on providing clear guidance for solving the geometric problems presented. Understanding these formulas is essential for accurate calculations.

CD is a line segemnt, ABCD is a trapezoid. Is that what you're trying to find the area & perimeter for?

Perimeter should be rather simple ... what do you get?

Area of a trapezoid is $\dfrac{h}{2}(b_1+b_2)$ where $b_1$ and $b_2$ are the parallel bases.

Where, exactly, are you having trouble?
