Question

The length of a rectangle is 6m more than its breadth and perimeter of rectangle is 128 m . Find dimensions of rectangle

Answer 1

b= x

l= x+6

2(l+b)=128

l+b. = 64

x+x+6=64

2x+6=64

2x= 58

x= 29

therefore;

breadth= 29m

length =29+6=35m

Answer 2

Let, breadth be x

Then, length = 6 + x

Perimeter = 128 m

According To Question:

2 ( 6 + x + x) = 128 m

=) 2 (6+2x)=128 m

=) 12+4x = 128 m

=) 4x = 116 m

=) x = 29 m

Now,

Length = 6 + Breadth = 35 m

Hence, the dimensions of the rectangle are 35 m and 27 m
