Question

Find the area and perimeter of rectangle having length=15cm breadth=7.5cm
​

Answer 1

Step-by-step explanation:

area of rectangle = length × breadth

so. area of rectangle = 15×7.5 = 112.5 cm²

perimeter of rectangle = 2(l+b)

perimeter of rectangle = 2(15+7.5)

= 2× 22.5

= 45 cm.

Answer 2

Question:-

• Find the area and perimeter of rectangle having length=15cm breadth=7.5cm

Given:-

• Length = 15cm
• Breadth = 7.5cm

To Find :-

• Perimeter of rectangle
• Area of rectangle

Solution:-

$\boxed{ \sf \blue{ Area \: of \: Rectangle }}$

$\begin{gathered}\begin{gathered}: \implies \underline{ \boxed{\displaystyle \sf \bold{\:Area \: of \: Rectangle\: = \: Length \: × \: Breadth }} }\\ \\\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}: \implies \displaystyle \sf \:Area \: of \: Rectangle\: = \: 15cm\: × \: 7.5cm \\ \\ \\\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}: \implies \displaystyle \sf \:Area \: of \: Rectangle\: = \: 112.5cm²\\ \\ \\\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}: \implies \underline{ \boxed{\displaystyle \sf \bold{\:Area \: of \: Rectangle\: = \: 112.5cm² }} }\\ \\\end{gathered}\end{gathered}$

$\boxed{ \sf \blue{ Perimeter \: of \: Rectangle }}$

$\begin{gathered}\begin{gathered}: \implies \underline{ \boxed{\displaystyle \sf \bold{\: Perimeter \: of \: Rectangle\: = \:2\:( Length \: + \: Breadth )}} }\\ \\\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}: \implies \displaystyle \sf \: Perimeter \: of \: Rectangle\: = \:2\: ( 15cm\: + \: 7.5cm ) \\ \\ \\\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}: \implies \displaystyle \sf \: Perimeter \: of \: Rectangle\: = \:2\: × \: 22.5cm \\ \\ \\\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}: \implies \displaystyle \sf \: Perimeter \: of \: Rectangle\: = \: 45cm \\ \\ \\\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}: \implies \underline{ \boxed{\displaystyle \sf \bold{\: Perimeter \: of \: Rectangle\: = \: 45cm}} }\\ \\\end{gathered}\end{gathered}$

Therefore:-

• Area of Rectangle = 112.5cm
• Perimeter of Rectangle = 45cm
