Question

find the area and perimeter​

Answer 1

Step-by-step explanation:

area = lx b and perimeter = sum of all sides

area of box 1

9x8 + 12 x 3 = 72+36 = 98cm²

perimeter = 12+ 8+ 9+ 4+ 3+ 12

48cm

figure 2

area = 2 x 14 + 4 x 2 + 5x 2

28+8+10

46 cm²

perimeter = 2+ 14+ 7+2+5+4+4+2+4+6

52cm

Answer 2

$\texttt \blue{PERIMETER:-}$

$\textsf{SUM OF ITS ALL SIDES}$

$\textsf \red {1ST FIGURE}$

$\texttt \blue{12+8+9+4+12+3=48cm}$

$\texttt \blue{PERIMETER OF 1ST FIGURE=45cm}$

$\texttt \blue{2ND FIGURE}$

$\texttt \blue{2+2+2+4+4+6+7+14=41cm}$

$\texttt \blue{PERIMETER OF 2ND FIGURE=41cm}$

$\textsf \blue{YOU HAVE FIND BY DIVIDING INTO 2 PARTS}$

$\texttt \blue{AREA OF 1ST FIGURE}$

$\textsf \blue{12×3+9×8}$

$\texttt \blue{AREA=98cm²}$

$\textsf \blue{TRY 2ND FIGURE}$
