Question 2. A. 34 cm</span></span>²<span><span>
Question 3. A. 144.5 cm</span></span>²<span><span> 

</span><span><u>Explanation </u>

</span><span><u>Question 1 </u>
The figure is a looks like a parallelogram of length 2.7 cm and a vertical height of 5.2 cm.
The formula for finding the area of a parallelogram is;
Area =length ×height
Area =2.7×5.2
Area =14.04 cm</span></span>²<span><span>

<u>Question 2 </u>
The figure is a triangle of base length 17 cm and a vertical height of 4 cm.
Area of a triangle = 1/2×length×height
=1/2×17×4=34 cm</span></span>²<span><span> 

<u>Question 3</u>
The figure is a combination of two figures, a rectangle and a triangle.
You should find the area of the 2 figures and then add them together.
Rectangle=length ×width
=13×9=117
Triangle =1/2×base×height
=1/2×11×(13-8)=1/2×11×5=27.5
Total area = 117 + 27.5 =144.5 cm</span></span>²<span><span>

Add the first 12 terms of this sequence:<br> 15, 45, 135, 405, 1215, ...
UkoKoshka [18]

Answer:

Step-by-step explanation:

a₁ = 15

a₂/a₁ = 45/15 = 3

a₃/a₂ = 135/45 = 3

...

It is a geometric sequence with a common ratio r=3.

Sum of first 12 terms = a₁·(1-r¹²)/(1-r)

= 15·(1-3¹²)/(1-3)

= 15·(-531,441)/(-2)

= 3,985,800

What is the perimeter of the triangle
KengaRu [80]

The perimeter of the triangle is 40 units

<h3>Perimeter of a triangle</h3>

From the question, we are to determine the perimeter of the given triangle

From the given diagram, we can observe that the triangle is a right triangle

The vertical length of the triangle is 15 units

and the horizontal length of the triangle is 8 units

Thus,

We can find the hypotenuse by using the<em> Pythagorean theorem </em>

Let the hypotenuse be h

Then,

h² = 15² + 8²

h² = 225 + 64

h² = 289

h = √289

h = 17 units

Now, for the perimeter of the triangle

The perimeter of a triangle is the sum of all its three sides

Thus,

The perimeter. P, of the triangle is

P = 15 + 8 + 17

P = 40 units

Hence, the perimeter of the triangle is 40 units
