Answer:

Perimeter is 4a - 10

Area is a^2 - 5a

Step-by-step explanation:

Two sides of the rectangle are "a" and two sides of the rectangle are "a-5"  add all four sides and you get a+a+a-5+a-5  Combine the like terms and you get 4a - 10.

The area is when you multiple the two sides together

A = lw

A - a(a-5) = a^2 - 5a
