In a system of nonlinear inequalities the solution set is the region where the shaded regions overlap.?
The answer depends on which area is shaded for each inequality. I always teach pupils to shade the unwanted or non-feasible region. That way the solution is in the unshaded area. This is much easier to identify than do distinguish between a region which is shaded three times and another which is shaded four times.
What does area equals side squared mean?
It is the way to calculate a given square's area. It is the definition of its area.
How do you calculate the surrounding area of an irregular shape?
The most direct way to calculate the area of an irregular shape is to superimpose it on graph paper, and then count the number of complete squares that it covers, and for squares that are only partially covered, estimate how much of the square is covered to the nearest simple fraction (a half, a third etc.). If you want the surrounding area rather than the area of the shape itself, you could calculate the total area and then subtract the area of the shape.
How do you calculate the surface area of a wall?
The same way you calculate the surface area of any other rectangle: Multiply the length of the wall by its height.
What is the main reason behind the invention of Heron's formula for finding area of triangle?
Probably Heron wanted a way to calculate the area of the triangle.
