Calculating Perimeter & Area of a Parallelogram & Triangle

In summary, the formula for calculating the perimeter of a parallelogram is 2(a+b), and the area of a triangle can be found using A = (1/2)bh. Perimeter involves finding the distance around the outer edge of a shape, while area involves finding the space inside the shape. The formula for calculating the perimeter of a parallelogram is different from that of a triangle, and the units used for perimeter and area will depend on the units of measurement for the shape's length and width. It is important to include units in the final answer.

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.

What is the formula for calculating the perimeter of a parallelogram?

The formula for calculating the perimeter of a parallelogram is: 2(a+b), where a and b are the lengths of the adjacent sides.

What is the formula for calculating the area of a parallelogram?

The formula for calculating the area of a parallelogram is: base x height, where the base is the length of one of the parallel sides and the height is the perpendicular distance between the two parallel sides.

How do you calculate the perimeter of a triangle?

To calculate the perimeter of a triangle, you add the lengths of all three sides together.

What is the formula for finding the area of a triangle?

The formula for finding the area of a triangle is: (base x height) / 2, where the base is the length of the triangle's base and the height is the perpendicular distance from the base to the opposite vertex.

What is the difference between perimeter and area?

Perimeter is the distance around the outside of a shape, while area is the measure of the space inside a shape.
