Parallelogram - A+p

Calculate the area and perimeter of a parallelogram if side a = 5.2 cm and height to side is va = 4 cm (it is a parallelogram, not a triangle)

Correct answer:

S =  20.8 cm²
o =  20.8 cm

Step-by-step explanation:

$$\begin{gathered} a=5.2\text{cm} \\ {v}_a=4\text{cm} \\ S=a\cdot v_a=5.2\cdot 4=20.8{\text{cm}}^2 \end{gathered}$$

$o=4\cdot a=4\cdot 5.2=20.8\text{cm}$
