Answer:
31.5 units^2
Step-by-step explanation:
Rectangle area (RA) = l × w
Triangle area (TA) = (bh)/2
RA = 3 × 7
RA = 21
TA = (7 × 3)/2
TA = 21/2
TA = 10.5
(Triangles are congruent as shown by the lines on each side of the triangle so I can calculate area of both of them together as I just did)
Add areas together
21 + 10.5 = 31.5
Answer:
Step-by-step explanation:
We have
square with sides <em>s = 3cm</em>
four triangles with base <em>b = 3cm</em> and height <em>h = 9cm</em>.
The formula of an area of a square:
The formula of an area of a triangle:
Substitute:
The Surface Area:
Answer:
Straight
Step-by-step explanation:
If the angle is flat or 180 degrees, it is straight
If the angle is like an L or 90 degrees, it is right
If the angle is less than 90 degrees, it is acute
If the angle is more than 90 degrees, it is obtuse
Hope this helps!!
