you where correct @peachpi i am sorry i got carried away i looked at a closed question and saw that you where correct

that means the perimeter = length *2 + width *2 So 42= 2x*2 +x*2= 4x + 2x = 6x if 6x = 42 then x= 42 divided by 6 therefore X= 7 ft right?

@peachpi i need your help
Rushwr

now we know X , That is width If width = 7ft Then length = 7*2 ft= 14ft right?
anonymous
  • anonymous
please listen to me @peachpi i am sorry
Rushwr
  • Rushwr
now we know both the length and the width now its just the matter of calculating the Area Area = length * width So Area= 7ft * 14ft = ? U find that LOL :) Did u understand this ?
