Answer 2

AnswEr :

➡ Length = 45$\large\frac{1}{2}$

➡ Length = $\large\frac{(45\times2+1)}{2}$

➡ Length = $\large\frac{90+1}{2}$

➡ Length = $\large\frac{91}{2}$

━━━━━━━━━━━━━━━━━━━━━━━━

➡ Breadth = 34$\large\frac{1}{2}$

➡ Breadth = $\large\frac{(34\times2+1)}{2}$

➡ Breadth = $\large\frac{68+1}{2}$

➡ Breadth = $\large\frac{69}{2}$

━━━━━━━━━━━━━━━━━━━━━━━━

━━━━━━━━━━━━━━━━━━━━━━━━

▣ Perimeter = 2(Length + Breadth)

▣ Perimeter = 2$\large({\frac{91}{2} + \frac{69}{2}})$

▣ Perimeter = 2$\large({\frac{91+69}{2}})$

▣ Perimeter = 2 × $\large\frac{160}{2}$

▣ Perimeter = 160 cm
