Question

A rectangular dog pen has an area of 108 square feet. The width of the pen is 9 feet. What is the length?

Answer 1

Answer:

$\sf \color{skyblue}{Length \: of \: pen \: is  \: 12 \: feet}$

• Step 1: Given area of the rectangular pen = 108 sq. ft. and width = 9 ft
• Step 2: Substitute in the formula for area of a rectangle = length x breadth

$\sf \pink{⇒ 108 = length \times 9}$

$\sf \red{⇒ length = \frac{108}{9}= 12}$

Answer 2

➵ Given :-

• Area of the pen = 108 sq feet .
• Width of the pen = 9 feet .

——————————————

➵ To Find :-

• Length of the pen = ?

——————————————

➵ Solution :-

⠀⠀⠀⠀

∓ Here, we will find the value of Lenght .

⠀⠀⠀⠀

• Now, let's solve step by step -----

⠀⠀⠀⠀

✪$\small\bf\pink{\:Area\:of\:Rectangle=Lenght×Breadth}$

⠀⠀⠀⠀

• By substituting the values -----

⠀⠀⠀⠀

⠀⠀$:\dashrightarrow \: \sf \red{Area \: of \: Rectangle} = \sf{L \times B} \\ \\ : \dashrightarrow \: \sf{108 =Length \times 9 } \\ \\ : \dashrightarrow \: \sf{Length = \cancel\frac{108}{9} } \\ \\ : \dashrightarrow \: \sf \pink{Length = 12}$

——————————————

➵ Hence :-

• Lenght of the pen = 12 feet .
