Length (L): 4w - 5
width (w): w
Perimeter (P) = 2L + 2w
140 = 2(4w - 5) + 2(w)
140 = 8w - 10 + 2w
140 = 10w - 10
150 = 10w
15 = w
Length (L): 4w - 5 = 4(15) - 5 = 60 - 5 = 55
Answer: width= 15meters, length=55 meters
Answer:
Dilation(Reduction)
Step-by-step explanation:
Parameterize this surface (call it
) by

with
and
. Take the normal vector to
to be

Then the area of
is



Answer:
264cm2
Step-by-step explanation:
the length of line in green = 5 cm
the length of line in yellow = 3 cm
the length of line in red = 6 cm
the length of line in white = 16 cm
the total area = 100 + 12 + 12 + 20 + 24 + 96 = 264 cm2
