Area = bh/2
(9.9 x 5.5)÷2 = 27.225 ft^2
Area is 92.13 and the perimeter is 47.42 i think it’s correct
You're trying to find constants

such that

. Equivalently, you're looking for the least-square solution to the following matrix equation.

To solve

, multiply both sides by the transpose of

, which introduces an invertible square matrix on the LHS.

Computing this, you'd find that

which means the first choice is correct.
