Question

find the dimension of a rectangular points if its perimeter is 350m and its length is 25 m more then its breathe​

Answer 1

Answer:

Breadth of a rectangle = x = 75 m

And

Length of a rectangle = (x + 25) = 100 m.

Step-by-step explanation:

Let the length and breadth of a rectangle be l and b respectively.

Given,

Perimeter of rectangle = 350 m

Let the breadth of a rectangle be x.

Length of a rectangle is 25 m more than breadth of a rectangle (given).

Then,

Length of a rectangle be (x + 25).

According to the question

Perimeter of a rectangle = 350 m

2 (l + b) = 350 m

2 (x + 25 + x) = 350 m

2 (2x + 25) = 350 m

4x + 50 = 350 m

4x = (350 - 50) m

4x = 300 m

x = 300/4 m

x = 75 m

(x + 25) m = (75 + 25) m = 100 m

Breadth of a rectangle = x = 75 m

And

Length of a rectangle = (x + 25) = (25 + 75) m = 100 m

Hence,

Breadth of a rectangle = x = 75 m

And

Length of a rectangle = (x + 25) = 100 m.

Answer 2

Answer:

dimensions of the rectangle is 100m×75m

Step-by-step explanation:

let the breadth of the rectangle be X

and the length of the rectangle is 25+X

we know that:

the perimeter of a rectangle=2(L+B)

350=2(X+25+X)

2(2x+25)=350

2x+25=350/2

2x+25=175

2x=175-25

2x=150

x=150/2

x=75

Hence the breadth of the rectangle is75m,and

the length of the rectangle is (25+75)m

=100m
