1. the length of a rectangular field is 42 meters more than the width. its perimeter is 600 meters. find its dimensions.
p=21+ 2w
coo = 21421+
ctangular piece of wood is 12 centimeters longer than it is wide. a strip 1 centimeter wide is cut off all around.
the decreases the area by 120 square centimeters. what were the original dimensions?
let w = original width.
1 = w+ 12 cm = original length
w-2 cm = new width
w + 12 cm - 2 cm = w+ 10 cm = new length
3. a rectangle's wi
length. its area is 338 square centimeters. what are its dimensions?
a=iw
348= 2l

 1) Length = 171 meters, width = 129 meters

Step-by-step explanation:

Length = w + 42

width = w

Perimeter = 600

Perimeter = 2(Length) + 2(width)

         600 = 2(w + 42) + 2(w)

         600 = 2w + 84   +  2w

         600 = 4w + 84

          516 = 4w

          129 = w

Length = w + 42

            = 129 + 42

            = 171

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

no not all of them.
