Answer:
The answer to your question is 13 u²
Step-by-step explanation:
We know that the small triangle is surrounded by right triangles so we can use the Pythagorean theorem to find the lengths of the small triangle
AD² = 3² + 2²
Simplify
AD² = 9 + 4
AD² = 13
AD =
Find the area of the square
Area = side x side
Area = AD x AD
Area =
Area = 13 u²
<u>Let's take this step-by-step:</u>
The mathematical name of this shape is a <u>right trapezoid </u>
⇒ <em>It is a trapezoid since the image shows a quadrilateral that </em>
<em> has two parallel sides and two non-parallel sides. It is a right </em>
<em> trapezoid because it has two rights angles</em>
<em> </em>The cube has <u>6</u> faces
⇒ <em>faces are the individual flat surfaces of an object</em>
<em> ⇒by looking at a picture of a cube, we see it has 6 sides</em>
<em> ⇒ (I attached an image of a cube below)</em>
Hope that helps!
