Hey there,
We know that area is the size of a surface
First of all, <span>To find the </span>area<span> of a rectangle, multiply the length by the width. In this question the length would be 90 meters and the width would be 45 meters.
</span>90 x 45 = Area
90 x 45 = 4050
<span>Area = 4050m</span>²
X^4+81=0 sorry if I got it wrong I apologize
X< -4
You need to do inverse operations and add 12 to both sides.
