answer
width = 98 cm
length = 105 cm
set up equations
the perimeter of a rectangle = 2W + 2L
p = 2W + 2L
the perimeter is also 406
406 = 2W + 2L
we know that the length of the rectangle is 7 cm longer than the width so
L = W + 7
substitute equations and solve for width
plug L into p = 2W + 2L to get
406 = 2W + 2(W + 7) distribute the 2 to the terms in the parentheses
406 = 2W + 2W + 14
406 = 4W + 14
392 = 4W
W = 98
substitute equations and solve for length
now that we know the width, we can substitute W in L = W + 7 to find length
L = W + 7
L = 98 + 7
L = 105
final dimensions
width = 98 cm
length = 105 cm

Answer:
Area of the shaded region = 23.33 in²
Step-by-step explanation:
Area of a sector = 
Where θ = Central angle subtended by an arc
r = radius of the circle
Area of the sector BCD = 
= 52.36 in²
Area of equilateral triangle BCD = 
= 
=
in²
= 43.30 in²
Area of the shaded portion in ΔBCD = 52.36 - 43.3
= 9.06 in²
Area of sector CAD = 
= 39.27 in²
Area of right triangle CAD = 
= 
=
= 25 in²
Area of the shaded part in the ΔACD = 39.27 - 25
= 14.27 in²
Area of the shaded part of the figure = 9.06 + 14.27
= 23.33 in²
