Answer:
The first prize is $800.
Explanation:
Third price = $50
The second price = $50(4) = $200
The first prize = 4($200) = $800
P = 2(L + W)
P = 44
L = W + 2
44 = 2(W + 2 + W)
44 = 2(2W + 2)
44 = 4W + 4
44 - 4 = 4W
40 = 4W
40/4 = W
10 = W
L = W + 2
L = 10 + 2
L = 12
A = L * W
L = 12
W = 10
A = 12 * 10
A = 120 square inches <===
Answer:
Area=210
perimeter=66
Step-by-step explanation:
A=a+b(h)/2
P=a+b+c+d
Answer:
200
Step-by-step explanation:
20% of a book = 40 pages
100% of a book = x pages
20/100 = 40/x Cross multiply
20x = 100*40 Combine the right
20x = 4000 Divide by 20
20x/20 = 4000/20 Do the division
x = 200 Answer
