The perimeter of the rectangle is 62m, the length is 18m. What is the area of this rectangle.

1. Let the second side of the rectangle be x m. Let’s find it if its length is 18 m, and the sum of all sides, that is, the perimeter is 62 m:
P = 2 (a + b);
2 (18 + x) = 68;
18 + x = 68/2;
18 + x = 34;
x = 34 – 18;
x = 16;
This means that the width is 16 m.
2. Find the area of a rectangle with a length of 18 m and a width of 16 m:
S = ab;
S = 18 * 16 = 288 m²;
Answer: the area of this rectangle is 288 m².
