What is the area of a trapezoid that has the bases of 1 1/4ft and 14 inches and a height of 3 inches.
Rom4ik [11]

The area of the trapezoid is 43.5 inches²

Step-by-step explanation:

The formula of the area of a trapezoid is A=\frac{1}{2}(b_{1}+b_{2})h , where:

  • b_{1} and b_{2} are the two parallel bases
  • h is its height

∵ b_{1} = 1\frac{1}{4} feet

∵ b_{2} = 14 inches

∵ h = 3 inches

- Change the length of b_{1} from feet to inches

∵ 1 foot = 12 inches

∴ 1\frac{1}{4} feet = 1\frac{1}{4} × 12 = 15 inches

∴ b_{1} = 15 inches

Substitute the values of b_{1} , b_{2} and h in the

formula of the area

∴ A=\frac{1}{2}(15+14)(3)

∴ A = 43.5 inches²

The area of the trapezoid is 43.5 inches²

serious [3.7K]

Answer:

q = 10

Step-by-step explanation:

\text{slope} =-3=\frac{q-4}{-7-(-5)} =\frac{q-4}{-2} \\\Longrightarrow -3=\frac{q-4}{-2} \\\Longrightarrow \left( -3\right)  \times \left( -2\right)  =q-4\\\Longrightarrow 6=q-4\\\Longrightarrow q=6+4\\\Longrightarrow q=10
