What is the area of parallelogram abcd in square units

My way of solving this if to make four triangles and one rectangle out of this shape.

Use AB, BC, CD, DA to make the triangles.
The left-overs make up a rectangle that has the area of 2x3, which is 6.

Triangle AB and CD are equivalent, they are both (1/2)(1)(3)=1.5 each, which add up to 3.

Triangle AD and BC are equivalent, they are both (1/2)(1)(4)=2 each, which add up to 4.

So, just add up the 6 from the rectangle and the 3 & 4 and you get 13.

The area of that parallelogram is 13.

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
