if u want help with that question..
here it is..
it meant..
draw a square.... with x = to the length of it's 4 sides...
it sed add 5 metres to one, and 10 to the other..
then u draw a rectangle to show the extension.
one side of the rectangle's length
must say x+5 which means... u gave that side... 5 more metres..
the same on the other side..
but this time u extended it by 10 metres..
so u say taht the other side is x+10
to get the the area..
u simply multiply the two sides together...
(x+10)(x+5) = x^2 + 10x + 5x + 15
then u simplify..
making it..
x^2 + 15x +15

if im wrong in anyway... please tell me....

I love the assistance that you guys are giving each other. Amazingly accurate explanation, but you are wrong in one way...the final answer. (x+10)(x+5)= x^2+15x+50. Hopefully this was just a typo and you have it correct on your test paper.
