Answer: 3173 mm² (Answer C)
Area of the bottom triangle = 1/2 x base x height
Area of the bottom triangle = 1/2 x 19 x 23 = 218.5mm²
Area of the top triangle = area of the bottom triangle
Area of the top triangle = 218.5mm²
Area of the 3 side rectangles = (23 x 38) + (19 x 38) + (30 x 38)
Area of the 3 side rectangles = 2736 mm²
Total Surface area = 218.5 + 218.5 + 2736 = 3173 mm²

Answer:
fourth option
Step-by-step explanation:
Given
= 
( cross- multiply )
y(w + 2) = 2z(2x - 1) = 4xz - 2z ( divide both sides by y )
w + 2 = 
( subtract 2 from both sides )
w = - 2
rationalise the denominator by multiplying both top and bottom by (8-5√3) then expand and simplify
Answer:
C(9,8) and r=2
Step-by-step explanation:
k:(x-9)^2 +(y-8)^2 =4
k:(x-p)^2 +(y-q) ^2 =r^2
p=9, q=8, r=2-radius
C(p,q)=C(9,8)-center
