Answer:

  38

Step-by-step explanation:

The graph shows all of the sides of the figure aligned with the axes except side ST. Its length can be found using the distance formula:

  d = √((x2 -x1)² +(y2 -y1)²)

  d = √((7 -(-5))² +(-2 -3)²) = √(144 +25) = 13

Then the perimeter is the sum of the side lengths:

  13 + 4 + 12 + 9 = 38

The perimeter of STUV is 38 units.

The Area of rectangle = 80 unit².

<h3>What is Area of rectangle?</h3>

The area can be defined as the amount of space covered by a flat surface of a particular shape. It is measured in terms of the "number of" square units (square centimeters, square inches, square feet, etc.) The area of a rectangle is the number of unit squares that can fit into a rectangle. Some examples of rectangular shapes are the flat surfaces of laptop monitors, blackboards, painting canvas, etc. You can use the formula of the area of a rectangle to find the space occupied by these objects. For example, let us consider a rectangle of length 4 inches and width 3 inches.

from figure (a)

DE= 40/8 = 5

BC= 100/5 = 20

Now,

AC= AB + BC=  8+ 20 = 28

CE= CD + DE = 10+5= 15

So, area of rectangle

= AC* CE

= 28* 15

= 420

Now, from figure (b)

CD= 24/12= 2

DE= 12/4 = 3

AC= AB+ BC= 14+ 4= 16

CE= CD + DE= 2+3 = 5

So, Area of rectangle= 16*5 = 80 unit²
