The perimeter of a rectangular plot is 300 m. Its width is 52 m.<br> What is its area?
madreJ [45]
5’096 m
If one side of the rectangle is 52m then you can assume that both sides would equal 104m. That leaves the other 2 sides to equal 196, and that means that one of the other sides would equal 98. The equation to find area is length x hight, so you’re gonna do 52 x 98 giving you 5’096. :) hope that helps!!

Bens living room is a rectangle measuring 9 yards by 150 inches. By how many feet does the length of the room exceed the width?
defon

Answer:

14.5 ft or 14 1/2 ft

Step-by-step explanation:

36in= 1 yard

9x36= 324in (I'm guessing this is the length)

324in (length) -150in (width)= 174in

12 in= 1 ft

174/12= 14 ft 6 in

6 inches is half a foot

14.5 ft or 14 1/2 ft

Justus has a flexible container that holds 200 milliliters of alr at a temperature of 300 kelvins and a pressure of 100 kilopasc
larisa [96]

Answer:

See below ~

Step-by-step explanation:

Based on the Ideal Gas Equation,

  • V ∝ T
  • V ∝ 1/P

Using T :

  • V₁/T₁ = V₂/T₂
  • 200/300 = 100/T₂
  • T₂ = 100/200 x 300
  • T₂ = 0.5 x 300
  • T₂ = 150 K

Using P :

  • P₁V₁ = P₂V₂
  • 100 x 200 = P₂ x 100
  • P₂ = 200 kPa

He can do this either by changing the temperature to <u>150</u> kelvins or by changing the pressure to <u>200</u> kilopascals.
