Question

Find the area and perimeter of the following rectangle guru angad education

Answer 1

1.

`P=2l+2w=2(11)+2(8)=22+16=38\text{ cm}`

2.

`\begin{gathered} A=11*11=121 \\ P=2(11)+2(11)=22+22=44 \end{gathered}`

3.

`\begin{gathered} A=8*6=48 \\ P=2(8)+2(6)=16+12=28 \end{gathered}`

4.

`\begin{gathered} A=7*2=14 \\ P=2(7)+2(2)=14+4=18 \end{gathered}`

5.

`\begin{gathered} 35=7* w \\ (35)/(7)=(7w)/(7) \\ w=5 \\ P=2(7)+2(5)=14+10=24\text{ units} \end{gathered}`
`\begin{gathered} 25=l*5 \\ (25)/(5)=(5l)/(5) \\ l=5 \\ P=2(5)+2(5)=10+10=20\text{ units} \end{gathered}`

6.

`P=11+18+9+3+3+8+5+7=64`
