Setler79 [48]

Answer:

Luis will have to pay $19.71 to cover the bulletin board with cork.

Step-by-step explanation:

We are given the following in the question:

Dimension of bulletin board:

Length, l = 1.1 m

Width, w = 0.56 m

Area =

$A = lw\\A = 1.1\times 0.56\\A = 0.616\text{ square meters}$

Unit cost = $32 per squared meter

Total cost =

$C=\text{Unit cost of cork}\times \text{Area of board}\\C = 32\times 0.616\\C = 19.71\$$

Thus, Luis will have to pay $19.71 to cover the bulletin board with cork.
