Question

Length of a rectangle is four less than the thrice of its breadth. The
perimeter of the rectangle is 110.​

Answer 1

Step-by-step explanation:

Let B be breadth of the rectangle

=>Length=3B-4

A.T.Q.

3B-4+B=110

4B=110+4

B=114/4

B=28.5

So,Length=28.5*3+4=85.5+4=89.5 and

Breadth=28.5

Answer 2

Answer:

2( l+b) = perimeter of rectangle

2( 3b-4 +b ) = 110

2(4 b -4 )=110

4b=55+4

b=59/4

b=14.75
