Answer:

  19.0 cm

Step-by-step explanation:

The length of each arc is given by ...

  s = rθ

where r is the radius of the arc, and θ is its central angle in radians.

The sum of the two arc lengths is ...

  s1 +s2 = (8 -4.5)(50(π/180)) +(8)(50(π/180)) = (16 -4.5)(5π/18) ≈ 10.0356

The sum of the two straight sides is ...

  2·4.5 = 9.000

So, the perimeter is ...

  P = arc lengths + straight sides = 10.0356 cm + 9.0000 cm ≈ 19.0 cm

The length of a rectangle is 5 more than the width. The perimeter is 120. What is the length, width, and area? Please HELP
Ad libitum [116K]

Answer:

l = 32.5 units, w= 27.5 units, A = 893.75 units²

Step-by-step explanation:

width is w

length is l = 5+w

P = 2( l+w) , substitute l for 5+w

P = 2(5+w+w)

P = 2(5+2w)

P = 10 +4w

P = 120

10 +4w = 120

4w = 120-10

4w = 110

w= 110/4

w= 27.5 units

l = 5+w = 5+ 27.5 = 32.5 units

A = l*w = 27.5 * 32.5 = 893.75 units ²
