Question

The area of rectangular field 836 sq. Cm one of its side 22 cm then what its perimeter

Answer 1

Answer:

120 cm

Step-by-step explanation:

Area of rectangle = 836 cm²

Breadth = 22 cm

We know that ;

Area of rectangle = length * breadth

⇒ 22 * l = 836

⇒ l = 836 /22

⇒ l = 38 cm

So,

Perimeter  = 2 (l + b)

                 = 2 ( 38 + 22 )

                 = 2 * 60

                 = 120 cm

Hence, the perimeter is 120 cm.

Answer 2

GIVEN:

• The area of rectangular field 836 sq. cm
• One of its side is 22 cm

TO FIND:

• What is the perimeter of the rectangle ?

SOLUTION:

Let the breadth of the rectangle be 'b' cm

We know that, the formula for finding the area of rectangle is:-

$\large{\boxed{\bf{\star \: AREA = LENGTH \times BREADTH \: \star}}}$

According to question:-

$\sf{\longrightarrow 836 = 22 \times b }$

$\sf{\longrightarrow \cancel\dfrac{836}{22} = b }$

$\bf{\longrightarrow 38 \: cm = b }$

• b = Breadth = 38 cm

We know that the formula for finding the perimeter of the rectangle is:-

$\large{\boxed{\bf{\star \: PERIMETER = 2(L+B) \: \star}}}$

According to question:-

$\sf{\longrightarrow PERIMETER = 2(22 + 38) }$

$\sf{\longrightarrow PERIMETER = 2 \times 60 }$

$\bf{\longrightarrow PERIMETER = 120 \: cm }$

• PERIMETER = 120 cm
