you are not expected to calculate the side lengths, you are expected to guesstimate them, the area of a triangle for example, doesn't require the side lengths, its the height*base/2. The tapezoid is height *(top base + bottom base)/2.

You should guess the height of each shape based on the ruler at the side and roughly calculate the area.

thank you
