Given that the area of the triangle is 12.6cm, calculate the perimeter of the triangle rounded
to 1 DP

could you reply to this with the question so i can ?

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.

step-by-step explanation:

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right
