Albert photograph has an area of 80 square inches the length of the photo is 1 1/4 the width which of the following to be the dimensions of the photograph

Sagot :

(length)*(width) = Area = 80

(length) = 1.25*(width)

replace what the length equals for the length
in the first equation to get:

1.25*(width)*(width) = 80
(width)^2 = 64   [divided 1.25 from both sides]
(width) = 8     [square rooted both sides]

plug this (width) back into the second equation

(length) = 1.25*(8) = 10

so (width) = 8
and (length) = 10
