Answer:

110 mm²

Step-by-step explanation:

The relevant area formulas are ...

A = LW . . . . . area of a rectangle with dimensions L and W

A = 1/2bh . . . area of a triangle with base b and height h

The figure can be divided into rectangles and a triangle as shown in the attachment. Working from the bottom up, the sum of the areas of the parts will be ...

(2×6) +(4×14) +(2×17) +1/2(4×4) = 12 +56 +34 +8 = 110 . . . square mm

What is the measure of one of the interior angles of the regular quadrilateral?

creativ13 [48]

Answer:

Measure of one of the interior angles ⇒ 90°

Step-by-step explanation:

If we are considering a regular polygon, all sides are ≅, respectively all angles are ≅ as well;

Now any quadrilateral has total interior angle measure of 360 degrees, provided they each can be split into two triangles and hence knowing a triangle is 180 degrees each, ⇒ 180 * 2 = 360°;

So if all these angles are ≅, we can claim that;

m∠ 1 = m∠ 2 = x = m∠ 3 = m∠ 4, where ∠1, 2, 3, and 4 are interior angles

x + x + x + x = 360 degrees ( ° ),

4x = 360°,

x = 90° = m∠ 1 = m∠ 2 = m∠ 3 = m∠ 4,

Solution; Measure of one of the interior angles⇒ 90°
