| From the condition, we know that the area of the rectangle is 32 cm2, and its length is 8 cm. In order to find the perimeter of this rectangle, we first of all find the width of the rectangle.
Let’s remember the formula for finding the area of a rectangle.
S = a * b;
Plug in the known values and solve the equation.
8a = 32;
a = 32: 8;
a = 4 cm width of the rectangle.
In order to find the perimeter of a rectangle, apply the formula:
P = 2 (a + b);
P = 2 (4 + 8) = 2 * 12 = 24 cm perimeter of the rectangle.
Answer: 24 cm perimeter of the rectangle.
