The area of the shaded portion is 512 ft²

Step-by-step explanation:

First we calculate the area of the full shape

Area = length × width

Length = 32 + 8 = 40 ft

Width = 8 + 8 = 16 ft

Area = 40 × 16

= 640 ft²

For the unshaded portion

Area = 8 × 8

= 64 ft²

Since we have two unshaded portions in the total shape

We add 64 + 64 = 128 ft²

Therefore the area of the shaded portion = total area of the shape - area of the unshaded portion

= 640 - 128

= 512 ft²

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%
