Uma pessoa comprou um terreno quadrado 81 m2 e deseja aumentar 19 m2 na area dele de que maneira ele continue em forma de quadrado qual sera o perímetro desse terreno

the new perimeter of the land is 40m

Step-by-step explanation:

The computation of the new perimeter of the land is given below:

Since the square plot is 81m^2

It could be increased by 19m^2

So the total would be

= 81m^2 + 19m^2

= 100m^2

Each side is 10m

Now the perimeter is sum of all sides

= 10m + 10m + 10m + 10m

= 40m

hence, the new perimeter of the land is 40m
