| Initially, we will compose an equation with which we determine the width of the rectangle.
x + 6 + x + x + 6 + x = 60.
4 x + 12 = 60.
4 x = 60 – 12.
4 x = 48.
x = 48/4.
x = 12 cm – becomes the width of this figure.
Now let’s calculate the length of the figure:
12 cm + 6 cm = 18 cm – becomes the length of the rectangle.
Knowing the length and width, we calculate the area, denoting it with a large letter S.
S = 12 cm * 18 cm = 216 cm2.
