1 rectangle has a circumference of 72cm. If you reduce the width by 6cm and keep the same length, the area will decrease by 120c
WARRIOR [948]

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

A town has a population of 19000 and grows at 4% every year. To the nearest year, how long will it be until the population will
larisa [96]

Answer:

1 year

Step-by-step explanation:

The population can be modelled by the equation:

P=P_0(1 + r)^{t}

From the question, the initial population is

P_0=19000

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:

43500=19000(1 + 0.04)^{t}

435=190(1.04)^{t}

\frac{435}{190}  = (1.04)^{t}

t =  \frac{  \ln(2.289) }{1.04}

t = 0.7965

To the nearest year, t= year
