The perimeter of a rectangle is 52 cm. If its width is 2 cm more than one-third of its length, find the dimensions of rectangle.

Jobisdone [24]

Answer:

(B) 18 cm x 8 cm

Step-by-step explanation:

let the length be x,

then the width is $\frac{1}{3}$ x + 2

2( $\frac{1}{3}$ x + 2 + x ) = 52

$\frac{1}{3}$ x + 2 + x = 26

$\frac{4}{3} x$ = 24

x = (24*3)/4

x = 18

then the length is 18 cm

and width is (1/3)*18 + 2 = 8

Therefore the dimensions are length:width = 18 cm : 8 cm

During 2002 and 2003, a total of 9316 people were infected with a specific virus. In 2003, 2.35 times as many people were infect

Alla [95]

X = 2002, y = 2003

x + y = 9316
y = 2.35x

x + 2.35x = 9316
3.35x = 9316
x = 9316 / 3.35
x = 2780.8 rounds to 2781 <=== year 2002

y = 2.35x
y = 2.35(2781)
y = 6535.3 rounds to 6535 <== year 2003
