Answer:  Perimeter = 66 cm and area =66\ m^2

Step-by-step explanation:

The perimeter of rectangle is given by :-

P=2(l+w), where l is length and w is width of the rectangle.

Given : A rectangle has a length of 5.50 m and a width of 12.0 m .

Then, the perimeter of rectangle :

P=2(12+5.50)\\\\\Rightarrow\ P=2(17.50)=35\ m

Also, area of rectangle is given by :-

A=l\times w=5.50\times12=66 \ m^2

Area of rectangle = 66\ m^2

There are 100 bacteria in a jar. Every day, the number of bacteria increases 25%. In approximately how many days will there be 5
algol [13]

Use compound interest formula

\\ \rm\Rrightarrow P(1+r/100)^t=500

\\ \rm\Rrightarrow 100(1+0.25)^t=500

\\ \rm\Rrightarrow (1.25)^t=5

\\ \rm\Rrightarrow log(1.25)^t=log5

\\ \rm\Rrightarrow tlog1.25=log5

\\ \rm\Rrightarrow t(0.097)=0.3

\\ \rm\Rrightarrow t=3.3\approx 3

Option A
