The rectangular field has an area of 48 A and its width is 150 m. Calculate the perimeter of the field.

Let’s denote by x the length of this rectangular field.
According to the condition of the problem, the width of this rectangular field is 150 m, and the area of this field is 48 hectares.
Since 1 hectare is 10,000 m², then 48 hectares is 48 * 10,000 = 480,000 m² and we can make the following equation:
x * 150 = 480,000.
We solve the resulting equation:
x = 480,000 / 150;
x = 48000/15;
x = 2300 m.
Find the perimeter p of this field:
p = 2 * (2300 + 150) = 2 * 2450 = 4900 m.
Answer: the perimeter of this field is 4900 m.
