Question

A 5 inch × 7 inch photograph is placed inside a picture frame. Both the length and width of the frame are 2x inches larger than the width and length of the photograph. Which expression represents the perimeter of the frame?

Answer 1

I think it's 2(L+B) so...2(7*9)=126

Answer 2

Answer:

(8x+24) inches.

Step-by-step explanation:

We are given that,

Dimensions of the photograph is 5 inch × 7 inch

It is given that the dimensions of the frame are $2x$ inches larger than the dimensions of the photograph.

Thus, the dimensions of the frame is (2x+5) inches × (2x+7) inches.

Since, the frame is in rectangular shape.

Perimeter of a rectangle = 2(Length + Width) = 2(2x+5+2x+7) = 2(4x+12) = 8x+24 inches.

Thus, the perimeter of the frame is represented by the expression (8x+24) inches.
