The attic floor, abcd in the model, is a square. the beams that support the roof are the edges of a block (rectangular prism) efghklmn. e is the middle of at, f is the middle of bt, g is the middle of ct and h is the middle of dt. all the edges of the pyramid in the model have length 12m.

calculate the area of the attic floor abcd.

The area of ABCD = 12² = 12 * 12 = 144 m²

Step-by-step explanation:

Given that ABCD in the model, is a square.

All the edges of the pyramid in the model have length 12m.

So, the length of one side of the square = 12 m

The area of the square = (side length)²

∴ the area of ABCD = 12² = 12 * 12 = 144 m²

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
