The trapezoid is another common shape. It’s slightly more challenging to measure. Begin by measuring both the parallel sides one by one. Add both of them. Divide the answer by 2, then multiply the number by the height of your trapezoid for getting its area.
On rare occasions, you may see areas which may be rectangle on one side & triangle on the other. Simply measure both the sections separately & add both the answers to get a single number.
