The area of a rectangle is 54 square inches and one side is 12 inches long. .find the perimeter of the rectangle

33 inches

Step-by-step explanation:

This is just a very simple geometry question.

Area is length x width.

So first, we have to find the width, which is 54/12=4.5.

Perimeter is all four sides added together.

We know opposite sides in a rectangle are congruent, so 2 sides would be 12 and 2 would be 4.5.

If we add them all together, it would be 9+9+4.5+4.5=33.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
