Question

(d) If the perimeter of a rectangle is 32, then the length is 13 and the width is 3.
Counterexample: length =
I width =

Answer 1

Answer:

• length = 10
• width = 6

Step-by-step explanation:

Any pair of dimensions that total 16 will give a rectangle with a perimeter of 32.

  P = 2(L +W)

  32 = 2(L +W)

  16 = L +W . . . . . . . divide by 2

This is true for L = 13 and W = 3. It is also true for L = 10 and W = 6, or any other pair of dimensions x and (16-x).
