Let the width be x -12 and length be x 2(x-12)+2(x) = 156 2x-24+2x = 156 2x+2x = 156 +24 4x = 180 x = 45 Therefore: width = 33cm and length = 45cm.
x=width x+25=length 4x+50=130 4x=80 x=20 width is 20 length is 45
Area of triangle is 0.5*b*h where: b = base h = height thus Area is: 0.5*(4x-3)*(2x) = (4x-3)*(x) = 4x2 - 3x
-2x = -4x + 24 -2x + 4x = 24 2x = 24 x = 24/2 x = 12
4x + 1 = 2x + 5 Subtract '1' frp, bpth sides Hence 4x = 2x + 4 Subtract '2x' from botbh sides 2x = 4 Divide both sides by '2' x = 2 The answer!!!!!!
