Answer:

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.
