## anonymous 4 years ago If the perimeter of a rectangle is 56 cm and the length of one side is 12 cm, what is the width of the rectangle?

sorry i thought i did the math wrong

4. anonymous

nevermind

5. anonymous

Perimeter $$=2 \times$$ (Length +width)

6. anonymous

so 56=2*(12+x), can you solve x from here?

7. anonymous

p=2(l+b); l=12 56=2(12+b) so, b=16
