The area of a rectangle is 42.15 square meters. if the length is 21 meters, what is perimeters of the rectangle?

perimeter = 46.014 meters

Step-by-step explanation:

The formula for determining the area of a rectangle is expressed as

Area = length × width

The area of a rectangle is given as 42.15 square meters. The length of the rectangle is given as 21 meters. This means that the width of the rectangle would be

Width = area/length = 42.15/21 = 2.007meters.

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(length + width)

Perimeter = 2(21 + 2.007) = 23.007 × 2 = 46.014 meters

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
