Find the area and perimeter perimeter of a rectangle with a width of 12 m and a length of 5 times its width.

1) Find the length of the rectangle.

The task says that it is five times larger than the width, which means that we multiply 12 by 5 to get 60.

2) Find the area of the rectangle by the formula and S = a * b

S = 60m * 12m = 720 (m2) – area.

3) Find the perimeter of the rectangle by the formula P = (a + b) * 2

P = (60m + 12m) * 2 = 144m – the perimeter of the rectangle.

Answer: the area of the rectangle is 720 (m2), the perimeter of the rectangle is 144m
