30 miles in 3/4 hours is faster.

Explanation:

20 times 1/2 is 10

Proof:

20=20/1

20/1x1/2=20/2
20/2=10

30 miles in 3/4 hour is 22 1/2

Proof:

30/1x3/4=90/4
90/4=22 2/4
22 2/4=22 1/2

Find the perimeter and the area of the polygon with the given vertices. W (11,2), X (11,8), Y (14,8), Z (14,2)
liberstina [14]

Answer:

The perimeter of the polygon = 18 units

The area of the polygon will be A=18 square units

Step-by-step explanation:

<u><em>Computing the Perimeter of the Polygon: </em></u>

Considering the polygon with vertices

  • W (11,2)
  • X (11,8)
  • Y (14,8)
  • Z (14,2)

As the polygon is drawn in coordinate plane as shown in figure a.

From the attached figure a, we can observe that

  • The length of the side WZ = 3 units
  • The length of the side ZY = 6 units
  • The length of the side WX = 6 units
  • The length of the side XY = 3 units

So, the perimeter of the polygon can be calculated by taking the sum of the lengths of all sides i.e.

The perimeter of the polygon = WZ + ZY + WX + XY

                                                  = 3 + 6 + 6 + 3

                                                  = 18 units

<u><em>Computing the Area of the Polygon: </em></u>

Area can be calculated by multiplying the length and width of the polygon.

A=lw

So, the area will be:

A=lw

A=(3)(6)

A=18

Therefore, the area of the polygon will be A=18 square units
