1040 feet.

Step-by-step explanation:

We know that , Perimeter of a rectangle = 2 (length +width)

As per given , we have

Length of football ground = $53\dfrac{1}{3}\text{yards}=\dfrac{53\times3+1}{3}\text{yards}=\dfrac{160}{3}\text{ yards}$

Width = 120 yards

Since, the football ground is rectangle in shape.

Then , Perimeter of the ground = $2(\dfrac{160}{3}+120)$ yards

$=2(\dfrac{160+3(120)}{3})$ yards

= $2(\dfrac{160+360}{3})$ yards

$=2(\dfrac{520}{3})$ yards

$=\dfrac{1040}{3}$ yards

Also, 1 yard =3 feet

i.e. Perimeter = $\dfrac{1040}{3}\times3=1040$ feet

Hence, the required perimeter is

Step-by-step explanation:

a + c = 1000

9a + 5c = 6680

9a + 9c = 9000

9a+ 5c = 6680

4c = 2320

c = 580

a+ 580 = 1000

a = 420

A = 420

C = 580

If you substitute the numbers into 9a + 5c = 6680, that should give you the right answer.
