How can (a + b)², be rewritten

Step-by-step explanation:

(a + b)^2 = a^2 + 2ab + b^2

This is a question on algebraic identities. If you wish to venture further into it/understand this topic better, you may want to follow my Instagram account (learntionary), where I post some of my own notes on certain topics and also some tips that may be useful to you :)

Henry's design would result in a larger flower bed because its area would be 2500 square feet.

Henry : perimeter (P) = 4awhere a is one side of the square
200 = 4a
200/4 = a
50 = aso each side of the square is 50 ft.
Area of a square (A) = a^2...where a is one side of the square...
A = 50^2 = 2500 ft^2

Liani : Area of rectangle (A) = length x width
A = L * W
A = 55 * 45
A = 2475 ft^2

so u can see that Henry's design would have a larger area then Liani's
