Answer 2

Answer:

The price of the area of land changes by 56%.

Step-by-step explanation:

Step 1:

Given data:

Let the initial length of land =l units

The initial breadth of land=b units.

Now let 'x' denote the cost of land per square units.

Step 2:

Area of land= l×b square units.

Price of land(P)= l×b×x= ₹ l x b x x.

Step 3:

Area of plot=1.2 l×1.3 b=1.56 lb square units.

The % change in area is:

1.56 lb-lb=0.56 lb

1.56-1=0.56 lb

Step 4:

The percentage increase in area is 56%.
