S = a b S\ =\ a\ \cdot\ b\ S = 8cm3cm =24cm2S\ =\ 8cm\cdot3cm\ =24cm^2

S = 8 30 = 240(cm)S\ =\ 8\ \cdot30\ =\ 240\left(cm^{ }\right) S = a b S\ =\ a\ \cdot b\ \ \ \

P = 2a + 2b P\ =\ 2\cdot a\ +\ 2\cdot b\ \ \ P =2 8 + 230 = 16 + 60 = 76 (cm)P\ =2\cdot\ 8\ +\ 2\cdot30\ =\ 16\ +\ 60\ =\ 76\ \left(cm\right)

P =2 8 +2 3 =16 + 6 = 22(cm)P\ =2\cdot\ 8\ +2\cdot\ 3\ =16\ +\ 6\ =\ 22\left(cm\right) P = 2a + 2b P\ =\ 2\cdot a\ +\ 2\cdot b\ \ \
