Question 617473
"The perimeter of a triangle is 28 m. If the length is two more than half the width, find the dimensions of the rectangle."

I'm assuming you're trying to find the dimensions of a rectangle? Well, here goes.

Right now we know that the perimeter is 28 m.

I always use let statements so,  let n = width      let {{{ 1/2 n+ 2 }}} = length
Then, since it's perimeter, you add 2 widths + 2 lengths 
{{{ 2n+2(1/2 n+2)=28 }}} then solve
{{{ 2n+n+4=28 }}} combine the n's
{{{ 3n+4=28 }}} subtract both sides by 4
{{{ 3n=24 }}} divide both sides by 3
{{{ n=8 }}}
So, the width is 8 m. and the length is 6 m. 

Also: square root of 19843223 is 4454.57


Hope I helped!
