Question

What is the area of parallelogram RSTU? 21 square units 24 square units 28 square units 32 square units

Answer 1

Answer: 21 square units

Step-by-step explanation:

We know that the area of parallelogram is given by:-

$A=height\times base$

Let US denote the height of the Parallelogram RSTU with corresponding base ST.

By counting the distance between the points using grids or by distance formula,

US=$|4-(-3)|=|7|=7\ units$

ST=$|-1-(-4)|=|-1+4|=|3|=3\ units$

Now, the area of parallelogram RSTU is given by:-

$A=7\times3=21\ \text{square units}$

Answer 2

Answer:21 units^2.

Step-by-step explanation:

I do the box method. I took the pic, put it into MSPaint, and drew a box around the... b o x.

Then I took the area of the drawn box (7*7) and subtracted the area of the triangles you get.

The one on the top was a 7*3 and divided the result by 2 to get 10.5.

The bottom one is also a 7*3 and you still get 10.5.

Add em together to get 21.

TL;DR: A
