What is the area of the rectangle?

Mathematics
1 answer:
DiKsa [7]3 years ago
4 0

Answer:

Area = 396 units²

Step-by-step explanation:

Let's assume:

Length = 2c - 5

Width = 5c + 9

Perimeter = 2(L + W) = 106 units

Thus:

2[(2c - 5) + (5c + 9)] = 106

Find the value of c

2[2c - 5 + 5c + 9] = 106

2[7c + 4] = 106

14c + 8 = 106

14c = 106 - 8

14c = 98

Divide both sides by 14

c = 98/14

c = 7

✔️Area of the rectangle = Length × Width

Area = (2c - 5)(5c + 9)

Plug in the value of c

Area = (2×7 - 5)(5×7 + 9)

Area = (14 - 5)(35 + 9)

Area = (9)(44)

Area = 396 units²

Murljashka [212]

Answer:

19,090\ people

Step-by-step explanation:

we know that

The equation of a exponential growth function is given by

y=a(1+r)^x

where

y is the population

x is the time in years since year 2015

a is the initial value

r is the rate of change

we have

a=10,600\\r=4\%=4/100=0.04

substitute

y=10,600(1+0.04)^x

y=10,600(1.04)^x

In the year 2040 the value of x is equal to

x=2040-2015=25\ years

substitute

y=10,600(1.04)^{15} =19,090\ people
