Answer:
Step-by-step explanation:
<u>Perimeter is</u>
<em>P = 2(l+w), where l= length, w = width</em>
<u>Substitute values to find the value of w:</u>
- 88 = 2(w + 16 + w)
- 2w + 16 = 44
- 2w = 28
- w = 14
Then
Dimensions are 14 ft and 30 ft
L = 2w + 6
p = 144
144 = 2w + 2(2w + 6)
144 = 2w + 4w + 12
132 = 6w
w = 22
l = 2(22) + 6
l = 50
The length is 50 feet and the width is 22 feet.
90 degree rotation clockwise : (a,b) --> (b,-a)
so... (24,-15) --> (-15,-24) is a 90 degree clockwise rotation
The first is x
the 2nd is 3 times the first or 3x
the third is 2 times long as the 2nd piece or 2(3x) or 6x
total length=1st piece+2nd piece+3rd piece
48.5=x+3x+6x
48.5=10x
divide by 10
4.85=x
3x=14.55
6x=29.1
the 3 pieces are 4.85cm, 14.55cm and 29.1cm
