I got 104 as my answer
The Johnsons framed a family picture to hang on the wall. The perimeter of the frame is 42 inches. Use the formula P = 2ℓ + 2w to find the length of the frame if the width is 10 inches.


A. 10 in.

B. 8 in.

C. 9 in.

D. 11 in.

Answer 1

D. 11 in.

Explanation:

p=2l+2w

42=2l+2 (10)

42=2l+20

-20 -20

22=2L

22/2 = 11

length = 11 inches

Your answer would be 104 if you do the math right

Step-by-step explanation:

2*42=84

2*10=20

84+20=104
