A = l * w. We can substitute the expressions for length and width into the equation for area ... values in the formula for perimeter, we will get. P = 2l + 2w. P = 2 (5) + 2 (3) P = 10+6 ... L = 18 cm. B = 7 cm. Perimeter of rectangle = 2 (length + breadth) P = 2 (L + B) ... Total time taken = Total distance walked * time taken to walk 1m.
