x = 10 feet.
Perimeter of a rectangle = 2(l + w)
Area of a rectangle = w*l
P = 60ft
Length = x
Width = 40-2x
A = ?
60 = 2(x+(40-2x)
60 = 2x + 80 - 4x
60 = -2x + 80
2x = 80 - 60
2x = 20
2x / 2 = 20 / 2
x = 10 -- length
Width = 40 - 2x ; where x = 10 ; 40 - 2(10) = 40 - 20 = 20.
P = 2(l + w)
60 = 2 (10 + 20)
60 = 2 (30)
60 = 60
Area = w * l
A = 20 * 10
A = 200 square feet

Answer:
this question is weirdly worded. i think you meant to type "three angles of a hexagon....." I'll do my best.
Step-by-step explanation:
sum of angles in a polygon: (n-2) 180° where n=#of sides of the polygon
(6-2) 180°
(4) 180°
720°
1a + 1a + 1a + 0.5a + 0.5a + 0.5a = 720°
4.5a = 720°
a = 720°/4.5
a = 160
0.5a = 80
Check
3(160) + 3(80)
480 + 240 = 720
72 × 1.4666666666667 = 105.6 feet per second
Let x = total emails in his inbox.
36% = 0.36
0.36x = 27. Divide each side by 0.36.
x = 75
