the demensions of a rectangle are 5y for the height, and 7y4 for the length. the question i need help with is asking me to simplify the equation for the perimeter and the area of this figure.

P = 2*5Y + 2(7Y  4),
P = 10Y + 14Y  8,
P = 24Y  8,
P = 8(3Y  1).
A = 5Y(7Y  4),
A = 35Y^2  20Y,
A = 5Y(7Y  4).
