Answer:
a) Triangle.
b) Triangle.
c) The area is 110 cm.
Step-by-step explanation:
The shape is given because it is a cross section of a Pyramid which we can see shaded in grey.
The area is given by the base times hight devided by 2. So 10cm * 22cm/2= 110cm.
Hope this helped ;)

2 terms so it is a binomial
We are given a circle with center O.
We can see that we have a radius OB of given circle.
OC and OE are another two radii.
EC is a diameter of the circle.
<em>Diameter is the segment that cut the circle at two points and passes through center.</em>
AB is a tangent of the given circle.
<em>A tangent is a segment that cut a circle at one point only.</em>
But the chord is GD.
<em>A chord of a circle is the segment that cut a circle at two points.</em>
<h3>Therefore, a chord in circle O is GD.</h3><h3 />
The area of a rectangle is:
A = length × width
A rectangular television screen has an area:
A = w² + 2w inches²
width = w
length = A / width = (w² + 2w) / w = w(w + 2) / w = <u>w + 2</u>
Ansver:
<h2><u>
length = w + 2</u></h2><h2><u>
</u></h2><h2><u>
</u></h2>
