Perimeter = 14Sqrt2 + 6Sqrt3 units

$14\sqrt{2} + 6\sqrt{3}$ $units^{2}$

Area = 21Sqrt6 units^2

$21\sqrt{6}$ $units^{2}$

Step-by-step explanation:

Perimeter = (2 * Length) = (2 * Width)

Area = Length * Width

Length = Sqrt18 + Sqrt32

Width = Sqrt27

Simplify Square Roots:

Square the square root to make it a rational (whole) number. Find a pair of factors, where one is a square number. Square root the factors.

Sqrt18^2 = 18 = 2 * 9 = Sqrt(2*9) =Sqrt2 * 3 = 3Sqrt2

Sqrt32 = 32 =2 * 16 = Sqrt(2 * 16) = Sqrt2 * 4 = 4Sqrt2

Sqrt27 = 27 = 3 * 9 = Sqrt(3*9) = Q3 * 3 = 3Sqrt3

Length = 3Sqrt2 + 4Sqrt2 = 7Sqrt2

Width = 3Sqrt3

Perimeter = (2 * 7Sqrt2) + (2 * 3Sqrt3) = 14Sqrt2 + 6Sqrt3 units

Area = 7Sqrt2 * 3Sqrt3 = (7 * 3) (Sqrt2 * Sqrt3) = 21Sqrt6 units^2

we know that

The inscribed angle is the half of the arc it comprises.

In this problem

m∠EFD=

we have

substitute the value

m∠EFD=

therefore

the answer is

m∠EFD=
