Question

if a rope is rope is 400 long is formed in a rectangle . if the breath of the rectangle is 25 cm what is its length .​

Answer 1

Answer:

175 cm

Step-by-step explanation:

perimeter= 2(l+b)=p

=2(l+25)=400

2 L+50(50 came by multiplying 2 and 25)

2L=350

L=350 upon 2=175cm answer.

Answer 2

Given,

Length of the rope used to form rectangle = 400 cm

Breadth of the rectangle = 25 cm

To find,

Length of the rectangle

Solution,

The length of the rope  used to form rectangle is nothing but the perimeter of the rectangle, as it surrounds the whole area occupied by the rectangle.

Perimeter of the rectangle = 2(l+b)

Here l = length and b = breadth

So let us substitute perimeter and breadth value in the formula.

2(l+25) = 400 cm

l+25 = 200

l = 200 - 25

l = 175cm

Hence, the length of the rectangle is 175cm.
