HELP :O

Answer 1

For 1) area of a rectangle = length*width

For 2) area of a triangle = (1/2)(base)(height)

For 3-4, combine like terms. For 3), -2sqrt(5) + 3sqrt(5) is

Notice how both terms have sqrt(5). Because -2 + 3 = 1, then -2sqrt(5) + 3sqrt(5) = 1sqrt(5) or just sqrt(5)

I’ll let you try 4 on your own
