PLEASE TELL ME THE ANSWER​

Answer 1

Question ::-

If the perimeter of a rectangle is 850 m and its length is 250 m , what its breadth?

Given ::-

• Perimeter of rectangle = 850 m
• Length = 250 m

To find ::-

• Find the breadth of rectangle ?

Solution ::-

• Perimeter of rectangle = 850 m

• Length = 250 m

• Breadth = b

Perimeter = 2( Length + Breadth)

850 = 2 ( 250 + b )

850/2 = 250 + b

425 = 250 + b

425 - 250 = b

175 = b

_______

• Breadth of rectangle is 175 cm

Answer 2

Given

• Perimeter = 850 m
• Length = 250 m

To find

• Breadth

Solution

We know perimeter of rectangle is 2(l+b)

• 2(250+b) = 850
• 500 + 2b = 850
• 2b = 350
• b = 350/2
• b = 175

So, Breadth of the rectangle is 175 m

Verification

• 2(l+b)=850
• 2(250+175)=850
• 425×2=850
• 850=850
