Area of triangles and quadrilaterals

Mathematics
1 answer:
pishuonlain [190]3 years ago
5 0
Formulas needed:

Square area = b^2
Rectangle area = bh
Triangle area = bh/2
Parallelogram = bh
Trapezoid area = a+b/2(h)
Rhombus area = pq/2

Even better; use online calculators.
To use these formulas, you need to substitute the values given for b,h,a,b,p or/and q and then solve to get area.

So for this example, since it's a rectangle, you use formula A = bh. Base is 5.1, and height is 6.

Substitute now.

A = bh
   = (5.1)(6)  (substitute)
   = 30.6       (multiply)

Therefore the area is 30.6 m^2. Don't forget the unit measurements, which is *measurement*^2.

How do i multiply fractions
Hatshy [7]
Best Answer:  <span> to multiply fractions you simply take the denominator of both fractions and multiply them, do the same to the numerator, and you have your answer.
ex.
2 5 10
-- * -- = ----
4 8 32

then, of course, you would need to simplify.

so the answer is

10(/2) 5
-------- = -----
32(/2) 16


To multiply mixed numbers, you need to convert them to improper fractions, multiply and then convert them back to a mixed number. For example:
2 1/2 x 5 1/3 = 5/2 x 16 /3

numerator 5 x 16 = 80 denominator 2 x 3 = 6

so now you convert 80/6 into a mixed number

80 / 6 = 13 and 2/6 or, reduced, 13 1/3. </span>
