hope you get it

Answer 2

Answer:

The mean of the two perimeters is 9 cm.

Step-by-step explanation:

The perimeter of a square is, P = 4a.

Compute the perimeter of the first square,

P₁ = 4 × 2 = 8 cm

P₂ = 4 × 5 = 10 cm

Compute the mean of the two perimeters:

$Mean_{P}=\frac{8+10}{2}=\frac{18}{2}=9$

Thus, the mean of the two perimeters is 9 cm.
