Question

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

Answer 1

1.

$A=l\times w=11\times8=88\operatorname{cm}\text{ }$$P=2l+2w=2(11)+2(8)=22+16=38\text{ cm}$

2.

$\begin{gathered} A=11\times11=121 \\ P=2(11)+2(11)=22+22=44 \end{gathered}$

3.

$\begin{gathered} A=8\times6=48 \\ P=2(8)+2(6)=16+12=28 \end{gathered}$

4.

$\begin{gathered} A=7\times2=14 \\ P=2(7)+2(2)=14+4=18 \end{gathered}$

5.

$\begin{gathered} 35=7\times w \\ \frac{35}{7}=\frac{7w}{7} \\ w=5 \\ P=2(7)+2(5)=14+10=24\text{ units} \end{gathered}$$\begin{gathered} 25=l\times5 \\ \frac{25}{5}=\frac{5l}{5} \\ l=5 \\ P=2(5)+2(5)=10+10=20\text{ units} \end{gathered}$

6.

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