HI!!!

anonymous · Answer

The perimeter of a rectangle is width + width + length + length 
So the perimeter is x + x + (x + 3) + (x + 3) 

Using perimeter = 58: 
x + x + (x + 3) + (x + 3) = 58 
4x + 6 = 58 
4x = 52 
x = 13cm 

So the width = 13cm and the length = 16cm

misty1212 · Answer

we need a variable 
what do you want to call the width?

btw the answer above is very nice, but it is not the answer to your question

misty1212 · Answer

name your variable and we can do it

anonymous · Answer

its 16

anonymous · Answer

x is fine :P
And @Starbucks there isn't a 16 in my multiple choice.

misty1212 · Answer

ok so we say the width is $x$ and the length is 5 more than 3 times the width, so the length is 
$$3x+5$$

misty1212 · Answer

then we add them up 
two of each
we get 
$$x+x+3x+5+3x+5=58$$ combining like terms gives 
$$8x+10=58$$

anonymous · Answer

my bad

misty1212 · Answer

solve that one for $x$ 
still one more step after that

misty1212 · Answer

can you solve 
$$8x+10=58$$?

anonymous · Answer

6?

misty1212 · Answer

yes 
but that is not the final answer

anonymous · Answer

Is it 23 inches? I did 3*6+5

misty1212 · Answer

you are asked for the LENGTH and we solved for the width
the length is 
$$3\times 6+5$$

misty1212 · Answer

yeah 23
