The error in finding the perimeter of the rectangle is that the length was not calculated correctly, as it is of 5 units.
What is the perimeter of a rectangle?
The perimeter of a rectangle of dimensions l and w is given by:
P = 2l + 2w.
From the graph, the dimensions are given as follows:
- l = 4 - (-1) = 4 + 1 = 5.
Hence the perimeter is:
P = 2l + 2w = 2(5) + 2(3) = 16 units.
The calculated length was of 4, hence the error in finding the perimeter of the rectangle is that the length was not calculated correctly, as it is of 5 units.
