Answer
the length is 20 cm and breadth is 16cm
Step-by-step explanation:
let, 2(a+b)= 72( as its the formulae of circumference)
here a is the length and b is the breadth
now total area is ab
according to the question
a(b-6)= ab-120
or -6a= - 120
so length is 20 cm
now by putting the value in the 1st eq we get
2(a+b)=72
or(a+b)=36
or 20+b=36
so breadth is 16 cm.
length is 20cm and breadth is 16 cm
(u can verify that easily)
thank u
Answer:
1 year
Step-by-step explanation:
The population can be modelled by the equation:

From the question, the initial population is

The annual growth rate is r=0.04
We want to find how long it will take for that population to reach 43500.
We substitute the values to get:





To the nearest year, t= year
