the area of a rectangular photograph is 35 square inches. If the width of the photo is 5 inches how tall is the photo

Vika [28.1K]

We know that:

Area= length*width

Plug in the stuff you know.

35= length(tall)*5

Divide both sides by 5.

7= length

The photo is 7 inches tall.

I hope this helps!
