The length of a rectangle is 9 cm more than its width. The perimeter is 82 cm. Find the length of the rectangle.

25cm.

Step-by-step explanation:

Length = x+9

width = x

Perimeter = 2*width + 2*length

Perimeter = x+x+x+9+x+9

Perimeter = 4x+18=82

                        -18   -18

4x=64

/4    /4

x=16 cm.

Length = x+9

16+9= 25cm.

required rate of return = 0.166 = 16.6%

step-by-step explanation:

under the capital asset pricing model (capm), the required or expected rate of return for a particular security or asset is given using the formula:

required rate of return = risk-free rate + beta*(market risk premium)

we are given that;

risk-free rate = 4% = 0.04

beta = 1.4

market risk premium = 9% = 0.09

we simply plug these values into the above formula;

required rate of return = 0.04 + 1.4*(0.09)

required rate of return = 0.04 + 0.126

required rate of return = 0.166 = 16.6%
