Question

find the breadth of a rectangular park whose perimeter is 1440 m and length is 620






the answer is 100​

Answer 1

Step-by-step explanation:

perimeter of rectangle = 2( L + B )

1440 = 2 ( 620 + B)

1440 / 2= (620 + B )

720 - 620 = B

B = 100

Answer 2

Given :

• Perimeter = 1440 m

• Length = 620 m

To find :

• The Breadth

According to the question :

Perimeter = 2 ( Length (l) + Breadth (b) )

⟹ 1440 = 2 ( 620 + b )

⟹ 1440 = 1240 + 2b

⟹ 2b = 1440 - 1240

⟹ 2b = 200

⟹ b = 200 / 2

⟹ b = 100

∴ Breadth = 100

Verification :

Perimeter = 2 ( Length + Breadth )

⟹ 1440 = 2 ( 100 + 600 )

⟹ 1440 = 200 + 1200

⟹ 1440 = 1400

Hence Verified !

So Its Done !!
