Diberikan:

  • The above figure below is made up of 3 squares and a rectangle. The side of each square is 8 cm.

Menecari:

  • Find its area and perimeter

Jawaban:

\circ{ \pink{ \sf{let's \: find \: the \: perimeter \: of the \: figure}}}

We Know, The side of the each square is 8cm, and the distance between each square is 8cm

Now, The perimeter of figure equals :

\longrightarrow \tt \: (8 \times 9 + 8 \times 2 + 8 \times 2 + 8 \times 5)cm \\ \\ \\ \longrightarrow \tt \: (72 + 16 + 16 + 40)cm \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \\ \longrightarrow \pink{ \boxed{\tt{ \: 144cm \bigstar}}} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:

{ \purple{ \underline{ \frak{Hence \: the \: perimetere \: of \: the \: figure = 144cm}}}}

\\

\circ{ \pink{ \sf{let's \: find \: the \: area\: of the \: figure \: now}}}

  • We know that,

➠ Area of a square = Side × Side

➠ Area of a rectangle = Length × Breadth !

\longrightarrow \tt \: area = 3(8 \times 8) +( 40 \times 8) {cm}^{2} \\ \\ \\ \longrightarrow \tt \: area \: = 3(64) + (320) {cm}^{2} \: \: \: \: \: \: \: \: \\ \\ \\ \longrightarrow \tt \: area = \pink{ \boxed{ \tt{520 {cm}^{2} \bigstar}}} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:

{ \purple{ \underline{ \frak{Hence \: the \: area\: of \: the \: figure = 520cm}}}}
