A trapezoid has a height of 6 feet. The measures of the bases are 12 units and 18

Alik [6]

The area of this trapezoid is 90 square feet.

<h3>Explanation : </h3>

Before we know the answer, let's we know the formula first. The formula for count the area of trapezoid is :

$\boxed {\bold {A = \frac {(a+b) \times h}{2}}}$

If :

A = area of trapezoid
a = bottom bases of trapezoid
b = top bases of trapezoid
h = height of trapezoid

Okay, let's we count its :

We know that :

a = bottom bases of trapezoid = 18 feet
b = top bases of trapezoid = 12 feet
h = height of trapezoid = 6 feet

Question : A = area = ... ?

Answer :

$A = \frac {(a+b) \times h}{2} \\ A = \frac {(12+18) \times \cancel6}{\cancel2} \\ A = 30 \times 3 = 90 \: {ft}^{2}$

Each side of the equilateral triangle shown is 3 inches long. What is the height of the triangle?

rodikova [14]

• measure of the side: s = 3 in

You can find the height h by this formula:

s · √3
h = ————
   2

3 · √3
h = ————
    2

   3√3
h = ———— in (exact value)
   2

Using √3 ≈ 1.73,

3 · 1.73
h ≈ —————
2

5.19
h ≈ ————
2

h ≈ 2.60 in (approximate value)

I hope this helps. =)
