The area of the floor is 128 m² with a length of 16 m and a width of 8 m.
What is an equation?
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depend on other variables while a dependent variable is a variable that depends on other variables.
Let x represent the width. The rectangle room is twice as long as it is broad, hence:
length = 2x, height (h) = 4.5 m
Area of the 4 walls = 2(length * height) + 2(width * height)
216 = 2(4.5 * 2x) + 2(x * 4.5)
27x = 216
x = 8 m
Length = 2x = 2(8) = 16 m
Area of floor = 8 * 16 = 128 m²
The area of the floor is 128 m² with a length of 16 m and a width of 8 m.
