The area of a rectangle can be found by multiplying the length times the width, or A = l * w. The perimeter of the rectangle can be found by adding together the length twice and the width twice. From the given information, we know that l = p and w = p + 4, where l represents the length of the rectangle and w represents the width of the rectangle.
A = l * w = p(p+4) = p^2 + 4p
P = 2l + 2w = 2(p) + 2(p+4) = 2p + 2p + 8 = 4p + 8
Therefore, the area of the rectangle is p^2 + 4p and the perimeter of the rectangle is 4p + 8.
Hope this helps!
