Question

Perimeter of a rectangular plot is it 70m .length is 25 m.what is the breadth of rectagular plot​

Answer 1

Answer:

10m

Step-by-step explanation:

let x be the breadth of plot

length of plot = 25m

Perimeter of rectangle = 2(l+b)

Perimeter of rectangle = 2(l+b)= 2(25+x)

Perimeter of rectangle = 2(l+b)= 2(25+x) = 50+ 2x

But the perimeter of the plot is 70m ( given)

therefore, 50 + 2x = 70

2x = 70 - 50

2x = 20

x = 20/2

= 10m

hence the breadth of the plot is of 10 m ans.

hope u got it

please mark me as the brainliest

Answer 2

Answer:

The Breadth of the rectangular plot is 10m.

Step-by-step explanation:

Given - Perimeter = 70m ; Length = 25m

To Find - Breadth of the plot

Solution-

We know,

Perimeter = 2 (l + b)

=> 70 = 2 (25 + b)

=> 70 = 50 + 2b

=> 70 - 50 = 2b

=> 20 = 2b

=> b = 20/2

=> b = 10m Ans
