The total area is:
A = Ab + Al
Where,
Ab: base area
Al: lateral area
We have then:
For the base area:
Ab = (2) * (2)
Ab = 4 units ^ 2
For the lateral area:
Al = (4) * (1/2) * (2) * (root ((1) ^ 2 + (3) ^ 2))
Al = (4) * (root (1 + 9))
Al = 4raiz (10) units ^ 2
Total area:
A = 4 + 4raiz (10)
Answer:
A = 4 + 4raiz (10)
Answer:
A = 57.97 cm²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = 
h (a + b)
where h is the perpendicular height and a, b the parallel bases
Here h = 6.2, a = 10.8 and b = 7.9, thus
A = × 6.2 × (10.8 + 7.9) = 3.1 × 18.7 = 57.97 cm²
In maths, the “>” sign means “greater than”, or “bigger than.” If we say A > B, that means (in English) “A is bigger than B.”
So, if A > B and B > C:
A is bigger than B, and B is bigger than C.
So the smallest would be C, since both A and B are bigger. Next is B, and biggest is A.
That is the order they would be in a number line: C - B - A
Answer:
19 sides
Step-by-step explanation:
Sum of angles of n-side polygon = 180 *(n - 2)
180 *(n -2) = 3060
Divide both sides by 180
n- 2 = 3060/180
n - 2 = 17
n = 17+2
n = 19
Answer:
90 degrees
Step-by-step explanation:
All trapazoids are equal to 360 degrees.
so we can make an equation 2x+x+x=360 (the other corner would also be x because its an unknown value)
to simplify, 4x=360
you divide into both sides (360/4)
you get 90
