Question 458402: The length of a rectangle is 2cm more than the width. the perimeter is 68 cm. find the length and the width

let the width of the rctangle be x cms
then length of the rectangle will be (x+2)cms
here given that primeter of the rectangle is 68 cm
then 2(x+x+2)=68
=>2*(2x+2)=68
=>4*(x+1)=68
=>x+1=17
=>x=16
hence the length of the rectangle is 18 cm and the width is 16 cm

Question 460504: The area of a rectagular garden is 162 square meters. The width is 3 metesr longer than one-third of the length. Find the lenth and the width of the garden.
I know Area is L x W; I know W = 1/3 x + 3 ; L = x
(1/3x + 3)(x)= 162
1/3 x2 + 3 x = 162
x2 + 9 x - 486 = 0
(X+27)(X-18) = 0
x = -27 x = 18
1/3 (18) + 3 (18)
6 + 54 = 162 (not true)
