THE LENGTH AND THE BREADTH OF A RECTANGULAR PARK ARE IN THE RATIO 5 : 2. IF ITS PERIMETER IS 168m, FIND ITS LENGTH AND BREADTH. (STEP BY STEP PLZ) (HOPE U ENJOY IT)

Length = 60m, breadth = 24m

Step-by-step explanation:

Let the length of the park be 5x and the breadth 2x.

5x+5x+2x+2x = 168

14x = 168

x = 168 ÷ 14

x = 12

Length (5x) = 12 × 5

                   = 60

Breadth (2x) = 12 × 2

                    = 24

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
