Find the perimeter of a rectangle of length 41 cm and breath 28 cm. What is the area of rectangle??

$\huge{\underbrace{\textsf{\textbf{\color{lightblue}{Answer:-}}}}}$

$\sf Given\begin{cases} &\sf{Length\;of\;the\; rectangle, \;l\;=\be{41\:cm}}\\&\sf{Breadth\;of\;the\;square,\;b\;=\bf{28\;cm}}\end{cases}$

$\boxed{ \sf \blue{ To \: Find : }}$

Area of the rectangle = ❓

Perimeter of the rectangle = ❓

$\green{\underline\bold{Now,}}$

$\green{\underline\bold{We \:know,}}$

$\boxed{ \sf \blue{ Area\: of \:a \:rectangle \:= \:l\:×\:b.}}$

= 41 × 28

= 1148 cm sq.

$\green{\underline\bold{And,}}$

$\boxed{ \sf \blue{ Perimeter\: of \:a \:rectangle\:= \:2\:×\:(l\:+\:b)}}$

= 2 (l + b)

= 2 (41 + 28)

= 138 cm

$\pink{\underline\bold{∴\: Area \:of \:the\: rectangle \:= \: 1148\: cm \:sq..}}$

$\pink{\underline\bold{ Perimeter\: of\: the\: rectangle \:= \:138.}}$

Answer 2

$\huge\bf{\pink{\underline{\underline{\mathcal{AnSwer࿐}}}}}$

Given:-

• length of the rectangle = 41 cm.
• breadth of the rectangle = 28 cm

To find:-

• Area of the rectangle

Formula to be used:-

$\underline{\boxed{\sf Area = length × breadth }}$

Solution:-

:$\implies$ $\sf Area = 41 × 28$

:$\implies$ $\sf Area = 1148 cm²$

hence, the required area is 1148 cm²

Additional information

Perimeter of the rectangle :-

$\underline{\boxed{\sf perimeter = 2 ( length + breadth) }}$

Area of square:-

$\underline{\boxed{\sf area = side² }}$

perimeter of square:-

$\underline{\boxed{\sf perimeter = 4×sides}}$
