Step-by-step explanation:
Length of rectangle is 140 m and its breadth is 100 m
Perimeter = sum of all sides
For rectangle, P = 2(l+b)
P = 2(140+100)
P = 480 m
Area = length × breadth
For a rectangle, A = lb
A = 140 × 100
A = 14000 m²
We need to write the length and breadth such that it has the same perimeter but a larger area.
Let the length is 110 m and breadth is 130 m.
Perimeter, P = 2(110+130)
P = 480 m
Perimeter is same as previous
Area, A = 110 × 130
A = 14300 m²
Area is more than the initial area.
Hence, this is the required solution.

Given:
First, let's move the -1 to the right side. When we add 
, we get 
.
Now we can cross multiply, multiply (3n)(8) and (7)(9)
Simplify the left side.
Simplify the right side.
Divide both sides by 24 to isolate n.
Simplify.
