<PRE><B>Question 1054040</B>
base(b) = 2x+3
:
height(h) = 4x+7
:
Perimeter(P) of the rectangle = 2b + 2h
:
200 = 2(2x+3) + 2(4x+7)
:
200 = 4x+6 + 8x+14
:
200 = 12x + 20
:
divide both sides of = by 4
:
50 = 3x + 5
:
3x = 45
:
x = 15
:
*************************************
base(b) = 2x+3 = 2(15) + 3 = 33
:
height(h) = 4x+7 = 4(15) + 7 = 67
:
check answers
:
200 = 2(33) + 2(67) = 66 + 134 = 200
:
our answer checks
