Step By Step Explanation:
Area Of Trapezoid:
[ Find 'a' & 'b' ]
a: 5 In.
b: 10 In.
Height: 11 In.
[ Insert Numbers Into Equation ]
[ Solve ]
5 + 10 = 15
15 ÷ 2 = 7.5
7.5 · 11 = 82.5
Step-by-step explanation:
The formula of an area of a trapezoid:
b₁, b₂ - bases
h - height
We have b₁ = 10in, b₂ = 5in and h = 11in. Substitute:
0.0183
The percentage of students, who received their DTaP vaccine is 95%.
