Question

What is the area of the quadrilateral with vertices at coordinates (-4,-3),(1,-3), (-2,1) and (3,1) to the nearest tenth of a square unit ?

Answer 1

Hi there!

I have attached a graph of the points below. The shape that is graphed is a parallelogram. The formula for a parallelogram is base x height. We know that one side of the parallelogram is 5 units, and by also counting, we can determine that the height is 4 units.

WORK:
A = 5 x 4
A = 20 units

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
