A poster is 3 inches long. it is 4 times as wide as it is long find the perimeter and area of the poster?

So we know that the width is 12 because 4 x 3 = 12. The formula to find the perimeter is Length + length + width + width. So you would do 3 + 3 + 12 + 12 = 30. Therefore the perimeter is 30 inches

Following are the calculation of the area and perimeter of the given poster:

Given:

Length of poster=3 inches

The width of the poster is 4 times wide as the length.

To find:

area=?

perimeter=?

Solution:

Length=[tex]\bold{3 \ inches}[/tex]

Width=[tex]\bold{4 \times 3 = 12\ inches}[/tex]

Using formula:

[tex]\bold{Area= length \times width} \\\\\bold{perimeter= 2(length+width)}[/tex]

Following are the calculation of the area and perimeter:

Area[tex]=\bold{ 3\times 12 = 36 \ inches^2}[/tex]

Perimeter [tex]=\bold{ 2(3+12)= 2(15)=30 \ inches}[/tex]

Therefore the answer is "36 and 30".
