The area of a triangle is 861 square cm. The length of the base is 82 cm. What is the height of the triangle?

Cerrena [4.2K]

Hi!

The equation to find the area of a triangle is...

(a = area
b = base
h = height)

$a = \frac{1}{2} bh$

Fill in the values that we already have.
$861 = \frac{1}{2}82*h$
Divide both sides by 1/2
$861/ \frac{1}{2} = \frac{1}{2}/ \frac{1}{2}82*h$
1722 = 82*h
Divide both sides by 82.
1722/82 = 82/82*h
21 = h

The answer is B. 21 cm

Hope this helps! :)

2. Area of parallelogram = base*height
A = 24*9
A = 216
3. Surface area of prism = 2(wl + hl + hw)
l = 15 , w = 3 and h = 4
2(3*15+4*15+4*3)
2(45+60+12)
2(117)
234
Surface area of rectangular prism is 234mm^2

Trevor took one of his friends out to lunch. The lunches cost $248.40 and he paid 12.5% sales tax. If Trevor left a 15% tip on t

bixtya [17]

He paid ...

-- The cost of the lunches (100% = 1.00 of it)

-- 15% of the cost as a tip (15% = 0.15 of it)

-- 12% of the cost as sales tax (12% = 0.12 of it)

Total that he paid = (1.00 + 0.15 + 0.12) = 1.27 of $248.40

= $315.47 .

Trevor is one generous guy !

How can turn a percentage to a fraction

Dovator [93]

Say if you have 11% and you want to turn it into a fraction all you got to do is put 11 as your numerator and 100 as your denomanator. Or if it is 75% you have to do the same but simplify and its would make 15/20 then simplify again and its 3/4
