Answer:

The answer to your question is x = 30; y = 14

Step-by-step explanation:

Data

JK = x            PR = 20

JL = 21           PQ = y

LK = 18           QR = 12

Process

1.- Find x

Use proportions to find it

                 JK/PR = LK/QR

Substitution

                 x/20 = 18/12

Solve for x

                  x = 20(18/12)

                  x = 360/12

                 x = 30

2.- Find y

                PQ/JL = PR/JK

Substitution

                y/21 = 20/30

Solve for y

                y = 21(20/30)

                y = 420/30

                y = 14

Answer:

2.0 x 10^{1}

Step-by-step explanation:

1. length = 3.2 x 10^{5} m

width = 1.6 x 10^{4} m

Area of a rectangle = length x width

                                = (3.2 x 10^{5}) x (1.6 x 10^{4})

                                = 5.12 x 10^{9} m^{2}

2. length = 1.28 x 10^{7} m

   width = 8 x 10^{3} m

Area of a rectangle = length x width

                                 = (1.28 x 10^{7}) x (8 x 10^{3})

                                 = 1.024 x 10^{11} m^{2}

\frac{Area of rectangle 2}{Area of rectangle 1} = \frac{1.024*10^{11} }{5.12*10^{9} }

                       = 20

                       = 2.0 x 10^{1}

Thus,

The area of rectangle 2 is 2.0 x 10^{1} times greater than the area of rectangle 1.
