In a rectangular garden, the length of which is 64m., 1120m2 or 35% of the total area is occupied by a berry. calculate the length of the fence around the entire garden?

1) Knowing that 1120 m ^ 2 is 35% of the total area, we will make a proportion, where x is the area of the garden: 1120: 35 = x: 100;

x = 1120 100: 35 = 3200 (m ^ 2);

2) Knowing the size of the garden area and the length, we find out what the width of the rectangular garden is equal to: a = S: b = 3200: 64 = 50 (m);

3) To calculate the length of the fence around the garden, define the perimeter of this area. To do this, we apply the formula for calculating the perimeter of a rectangle: P = (a + b) 2 = (64 + 50) 2 = 228 (m).

Answer: the length of the fence around the garden is 228 m.
