IrinaK [193]

Answer:

Area = 6.5p

Step-by-step explanation:

Given

Area\ of\ Old = p

Area\ of\ New = 6.5 * Area\ of\ Old

Required

Write an expression for the area of new post office

From the question, we have the following:

Area\ of\ Old = p

and

Area\ of\ New = 6.5 * Area\ of\ Old

Substitute p for Area of Old in the second equation

Area\ of\ New = 6.5 * p

Area\ of\ New = 6.5 p

Hence, the expression is:

Area = 6.5p
