A = L*W
216 ft² = L*(9 ft)
(216 ft²)/(9 ft) = L
24 ft = L

The other dimension is 24 ft.

The perimeter is 2*(9 ft +24 ft) = 66 ft.

x = 4

4x - 6=10

4x = 10 + 6

4x = 16

$x = \frac{16}{4}$

x = 4 ← the missing value

Therefore the the solution is (4,-6) of the equation 4x+y=10 .

Hope this helped You!
