Answer:
10
Step-by-step explanation:
let the number be n then half the number is n, then
n + n = 15
Multiply through by 2 to clear the fraction
2n + n = 30, that is
3n = 30 ( divide both sides by 3 )
n = 10
Thus the number is 10
The side is (2x+3)? then the area is:
(2x+3)(2x+3) = 4 x^2 + 12 x + 9 if x = 6 then
Area = 4(36)+12(6)+9
= 144 + 72 + 9
= 225, too big :(
