A 4 by 5 inch photo is enlarged by multiplying every

dem82 [27]

Answer:

Perimeter ratio = 2:1

Area ratio = 4:1

Step-by-step explanation:

Perimeter

Perimeter of the smaller photo = $2l+2w$

$=2(5)+2(4)$

$=18$ inches

Perimeter of larger photo = $2l+2w$

$=2(10)+2(8)$

$=36$ inches

Ratio:

Perimeter of larger photo : perimeter of smaller photo = $36:18$

$=2:1$

Area

Area of smaller photo = $lw$

$=5\times4$

$=20$ inches²

Area of larger photo = $lw$

$= 10\times8$

$=80$ inches ²

Ratio

Area of larger photo : area of smaller photo = $80:20$

$=4:1$

∴The ratio of the perimeters = 2:1, and the ratio of the areas = 4:1

Hope this helps :)
