count the boxes on the grid where it asks for each such as b1 should be 6 so b2 = 10 and h = 5 by counting boxes upwards to find height. Now it asks you to find area of parallelogram so we have b2 + b1 as our bottom and b1 + b2 as our top which are equal = 16 and height is the same = 5 this happens after we combine both trapezoids together as shown in step 5. Step 6 they are asking for are of parrellelogram which is similar to a recatangle L times W which is 16 times 5 gives you 80 then divide this by 2 to find the trapezoids area which is 40.
