Question

Pleae help me do this need an A!!!!!

Answer 1

Step-by-step explanation:

Length of one side is 26 and both sides combined for the length is 52.

Answer 2

`a) \quad l = (P-2w)/(2)`

`b) \quad 26 \ inches`

Step-by-step explanation:

Perimeter = 2(Length + Width)

In short form:

P = 2l + 2w

Here make "l" the subject:

`\rightarrow P = 2l + 2w`

relocate term w

`\rightarrow P-2w = 2l`

dividing both sides by 2

`\rightarrow (P-2w)/(2) = l`

Now find the length of picture frame:

Given: P = 84 inches, W = 16 inches

`\rightarrow l = (84-2(16))/(2)`

evaluate

`\rightarrow l =26`

Hence, the length of the picture frame is 26 inches.
