1). "If 1 bogus = 15 zing, 42 klang = 25zing, 10 klang = 88 zoot, how many bogus make 1 zoot?"
2)."Find the dimensions of a rectangle whose area is 240cm2 and perimeter is 62cm."
The area of a rectangle is $\displaystyle A\,=\,l\,\cdot\,w$
The perimeter of a rectangle is $\displaystyle P\,=\,2l\,+\,2w$
So we know the area is 240.
Using the area equation we get: $\displaystyle 240\,=\,l\,\cdot\,w$
Also we know the perimeter is 62.
Utilizing the perimeter equation we get: $\displaystyle 62\,=\,2l\,+\,2w$
So we have the system:
$\displaystyle 240\,=\,l\,\cdot\,w$
$\displaystyle 62\,=\,2l\,+\,2w$
The dimension are l and w. Solve for both using any methods you've learned about systems.
