Answer 1

Answer:

Given:

The length of a rectangle is 6 less than twice its breadth if the perimeter of the rectangle is 54.

To find:

Find its length & breadth.

Solution:

⚫Let breadth be x

⚫Let length of rectangle= 2x -6

⚫Perimeter of rectangle= 54.

Therefore,

We know that, perimeter of rectangle;

=) 2(length+breadth)

So,

=) 2(2x-6 + x) = 54

=) 2(3x -6) = 54

=) 6x -12 = 54

=) 6x = 54 +12

=) 6x = 66

=) x = 66/6

=) x = 11

Thus,

Breadth,x = 11

Length, 2x -6 = 2×11-6= 22 -6 = 16
