Answer:
A ≈ 25.1 cm²
Step-by-step explanation:
the area (A) of the sector is calculated as
A = area of circle × fraction of circle
= πr² ×
= π × 6² ×
= 36π ×
= 18 ×
= 2 × 4π
= 8π
≈ 25.1 cm² ( to the nearest tenth )

Let's say, the amount that each side was increased was "a"
so, it was 5 wide and 12 long, now it's 5+a wide and 12+a long
we know the area is 120, so whatever "a" is, we know that
(5+a)(12+a) = 120
so
use those factors, solve for "a"
