Answer 2

$\mathbb{QUESTION}$

$\text{a table top measures 5m by 3m 50cm .what is its area in square meters​}$

$\mathbb{ANSWER}$

$\textsf{PERIMETER OF RECTANGLE=2(L+B)}$

$\textsf{4sides-2 lengths ,2breadths}$

$\textsf{=2L+2B\\=2(L+B)}$

$\boxed{\textsf{=2(L+B)}}$$\to 1$

$\text{length-5m=500cm,breath-3.50m=300cm}$ $\textbf{(conversion scale-1m=100cm )}$

$from \to1\:\: \textsf{2(L+B)}$

$\\=2(500+350)\\=2(850)\\=2(1700)$

$=3400cm$

$3400cm=34m$ $\textbf{(conversion scale-100cm=1m )}$

$\boxed{\textsc{34m}}$

$\textsf{AREAOF RECTANGLE=L x B}$

$\textsf{500 x 350 }$

$175000 cm$

$17.5 m^2$

$\boxed{17.5 \:\:m^2}$
