Answer:
C.) The perimeter is doubled and the area is quadrupled.
Step-by-step explanation:
Original square: side = 4
Area = side^2 = 4^2 = 16 square units
Perimeter = 4 * side = 4 * 4 = 16 units
Larger square: side = 8
Area = side^2 = 8^2 = 64 square units
Perimeter = 4 * side = 4 * 8 = 32 units
Comparison of areas:
(larger square area)/(original square area) = 64/16 = 4
Comparison of perimeters:
(larger square perimeter)/(original square perimeter) = 32/16 = 2
Answer:
C.) The perimeter is doubled and the area is quadrupled.
3.14 that is the answer i divided 22 by 7 <span />
Answer:
2714 mm3
Step-by-step explanation:
W= width
L= length= 2W-4
Perimeter= 70
FIND WIDTH:
P= 2(L + W)
P= 2L + 2W
substitute 2W-4 for L
70= 2(2W-4) + 2W
multiply 2 by all in parentheses
70= (2*2W) + (2*-4) + 2W
70= 4W - 8 + 2W
combine like terms
70= 6W - 8
add 8 to both sides
78= 6W
divide both sides by 6
13= W
FIND LENGTH:
substitute w=13 to find width
L= 2W-4
L= 2(13)-4
L= 26-4
L= 22
CHECK:
P= 2(L + W)
70= 2(22 + 13)
70= (2*22) + 2(13)
70= 44 + 26
70= 70
ANSWER:
length= 22 inches
width= 13 inches
Hope this helps! :)
