Find the area of rectangles on a grid. Explore how the formula works. First, estimate the area of a rectangle on a grid. Second, work out the correct formula for finding area by placing rows and columns of squares inside the rectangle. Then, compare the actual area of the original shape with your first estimate. Practise applying the formula directly to a range of rectangles. This learning object is the first in a series of two objects that progressively increase in difficulty.
