Answer:
x + 2/5 = 4
subtract 2/5 from both sides
That is
x + 2/5 - 2/5 = 4 - 2/5
x = 4 - 2/5
x = 18/5 or 3 3/5 as a mixed number

Answer:
A₁ = 950 mm²
Step-by-step explanation:
region 1 is a trapezium with area (A₁ ) calculated as
A₁ = h (b₁ + b₂)
where h is the perpendicular height between bases and b₁, b₂ the bases
here h = 38 , b₁ = 30 and b₂ = 20 , then
A₁ = × 38 × (30 + 20) = 19 × 50 = 950 mm²
