Answer:
He will earn 42$
Step-by-step explanation:
18 divided by 2.54
X = whole number
Z = fraction numarater
Y = fraction denometer
you can do
X = X/1
Z and Y = Z/Y
X/Z = C(the new numartater)
Y/1 = Y
C/Y
formula is
((a+b)/2)*h(height)
a and b - parallel sides
so answer is
15+23= 38
38/2 = 19
19* 9 = 171
