Question 1118798
-------------------
(1)
The perimeter of a rectangle is 94 m. The width of the rectangle is 7 m less than the length. Find the length and width of the rectangle.
-------------------

If use L for length, then perimeter dimensions description is {{{2L+2(L-7)=94}}};
.
.
{{{system(L=27,and,L-7=20)}}}



-------------------
(2)
The perimeter of a triangle is 36 ft. One side of the triangle is 2 ft longer than the second side. The third side is 4 ft longer than the second side. Find the length of each side.
-------------------


<pre>
side 1         x+2
side 2         x
side 3         x+4
perimeter      36
</pre>
{{{(x+2)+x+(x+4)=36}}}
{{{3x+6=36}}}
{{{3x=30}}}
{{{x=10}}}
