Answer 2

area of square = a^2
a is the length of the side

Answer 3

so in this case a = (x + 1)

Answer 4

area of square = (side)*(side)

in this case, the side is x+1, so,

area of square = (x+1)*(x+1)

I'll let you expand that out

Answer 5

and u know
(a + b)^2 = ??

Answer 6

x2+2x+1?

Answer 11

yup good work :)))

Answer 12

so that should be the answer?

Answer 13

yes x^2+2x+1 is the area of the square

Answer 14

thankz

Answer 15

no problem
