What is the area for this question?
kykrilka [37]

Height of the figure is 12 ft.

Solution:

In this image parallel sides and area are given but height is not given.

We have to find the height of the figure.

Given image is a trapezoid.

Parallel sides = 4.2 ft and 9 ft

Area = 79.2 ft²

Area of the trapezoid = \frac{1}{2}\times \text{Sum of the parallel sides} \times \text{height}

$79.2=\frac{1}{2}\times {(4.2 + 9)}\times {h}

$79.2=\frac{1}{2}\times 13.2\times {h}

79.2 = 6.6 × h

Divide by 6.6 on both sides, we get

12  =  h

Switch the sides of the equation.

h = 12

Height of the figure is 12 ft.

Answer:

1/4 or 0.25

Step-by-step explanation:

Isn't latex a devil?

You want to know the probability of a blue marble.

Formula

P(blue) = #Blue / # Total

Givens

#Blue = 333

#Total = 333 + 444 + 555 = 1332

Solution

P(blue) = 333 / 1332      Divide by 111

P(blue) = 3/12

P(blue) = 1/4 or 0.25
