Answer:

5/7

Step-by-step explanation:

3-1 2/7

3=21/7 (by multiplying denominator)

1 2/7=16/7 (by multiply 1 and 7. Then add to 2)

21/7 - 16/7 = 5/7

Area of triangles and quadrilaterals
pishuonlain [190]
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.
