B.204 square inches

C.2016 cents

Step-by-step explanation:

We are given that Jared sells square frames of various sizes made of wood .To find the area of a frame ,Jared uses the formula

Where s=Length of a side of the frame

w=Width of the frame

B.We are given that length of each side=s=20 inches

Width of frame=w=3 inches

Substitute the values in the above given   formula

Then, we get

A=

square inches

Hence, area of frame=204 square inches

C.We are given that

Cost of 1 square inch=18 cents

Length of each side of frame=s=16 inches

Width of frame=w=2 inches

Substitute the values in the given above formula

Then ,we get

square inches

Cost of 112 square inches==2016 cents

Hence, he will charge for a frame =2016 cents

all it means is function 3
