0 1 C 1. The students recorded the percentage cover of different plant4 species and
light intensity at distances of 0 m, 2 m, 4 m, 6 m, 8 m, and 10 m5from the tree.
Calculate the total area sampled if the quadrat size was 0.5 𝑚𝑚 6 × 0.5 𝑚𝑚 and
was placed at six locations along the transect. Show your working.
