Question

which expression is equivilent to the area of metal sheet required to make this square shape traffic sign one side is x+1 possible answers are
x2+2x+1
x2+x+1
x2+2x
x2+1

Answer 1

ok well, how many sides does a square have?
are the sides equal or do they differ in length?

Answer 2

4 sides all equal

Answer 3

yes so if one side is x+1, all other 3 sidses are also x+1

Area of a rectangle = length x width

Answer 4

so it's \[x ^2+1\]?

Answer 5

no, the length there is (x+1)
the width there is (x+1)

so the Area will be (x+1)(x+1)

Answer 6

length times width

Answer 7

possible answers are equivilent to the area
x2+2x+1
x2+x+1
x2+2x
x2+1 thats why I thought it was x^2+1 am I wrong ?

Answer 8

well, what's (x+1)(x+1) ?

Answer 9

the length is (x+1)
the width is (x+1)

the Area is length times width, so, what's (x+1)(x+1)?

Answer 10

x^2+1

Answer 11

hehe

Answer 12

hmmm would you say that \( \bf (x+1)(x+1) \implies (x+1)^2\ \ \ ?\)

Answer 13

a x a = \(a^2\)

Answer 14

yes
