Question

perimeter of a rectangular field is 72 cm. if the length is 20 cm find its breadth​

Answer 1

$\huge{ \boxed{ \boxed{ \mathfrak{AnsweR}}}}$

$\boxed{ \sf{Breadth \:of\: rectangular\: Field\:= 16 cm }}$

Step-by-step explanation:

$\huge{ \boxed{ \boxed{ \underline{ \underline{ \textsf{ \textbf{ GiveN}}}}}}}$

• Perimeter of rectangular field = 72 cm

• Length = 20 cm

$\huge{ \boxed{ \boxed{ \underline{ \underline{ \textsf{ \textbf{To\:Find }}}}}}}$

• Its Breadth

$\huge{ \boxed{ \boxed{ \underline{ \underline{ \textsf{ \textbf{SolutioN}}}}}}}$

• Let the Breadth be x

We know that Perimeter = 2 ( Length + Breadth )

• Now substitute the value of perimeter, Length and Breadth

• Perimeter = 2 ( Length + Breadth )

• 72 = 2 ( 20 + x )

• 72 = 2 × 20 + 2 × x

• 72 = 40 + 2x

• 72 - 40 = 2x

• 32 = 2x

• x = $\bf \frac{32}{2}$

• x = 16

$\boxed{ \sf{Breadth = x = 16 cm }}$

To check our answer we have to substitute the value of Breadth , Length and perimeter in the equation and check whether our answer is 72

• Perimeter = 2 ( Length + Breadth)

• 72 = 2 ( 20 + 16 )

• 72 = 2 × 36

• 72 = 72
