y= 7/4

10/8 = 5+x/5

50=40+8x

x = 8/10 = 4/5

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

Debora [2.8K]

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:-

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