Question

The perimeter of a rectangular field is 750m. If the length of the field is 250m then breadth is​

Answer 1

Answer:

p = 2(l+b)

given perimeter=250m

l=75m

2(l+b)=250

2(75+b)=250

75+b=250÷2

75+b=125

b=125-75

b=50

now area = l×b

75×50

answer is 3750m²

Answer 2

• Breadth of rectangular field is 125 m.

Explanation:

To find:-

• Breadth of rectangular field.

Solution:-

Given that,

Perimeter of rectangular field is 750 m.

Length of rectangular field is 250 m.

Let, Breadth of rectangular field be x.

$\boxed{\bold{Perimeter \:of \: rectangle = 2(l + b)}}$

• Here, l and b are length and breadth of rectangle.

➝ 750 = 2×(250 + x)

➝ 750 = 500 + 2x

➝ 750 - 500 = 2x

➝ 250 = 2x

➝ 250/2 = x

➝ 125 = x

Or, x = 125

Verification:-

➝ 750 = 2×(250 + x)

• Put x = 125.

➝ 750 = 2×(250 + 125)

➝ 750 = 500 + 250

➝ 750 = 750

Hence, Verified!!.

We have taken Breadth of rectangular field be x. So, Breadth of rectangular field is 125 m.
