If all the side on the square are 2.5 cm then you would multiply 2.5 times 4 (we get the four from the number of sides on the shape) and your answer is 10 cm
Answer:
370.1946711 yard ^2
Step-by-step explanation:
The figure is made out of two shapes, a square and a semicircle.
area of a circle is pi r^{2}
but in this question we have half of the cirlce therefore = 0.5 pi r^{2}
area of square = s * s
that makes the equation:
0.5* pi * (12)^{2} + 12^{2}
= 360.1946711
Answer:
Figure 1: x = 120°
Figure 2: x = 54°
Figure 3: x = 64°
Step-by-step explanation:
Every triangles interior angles will add up to 180°
Figure 1: 30 + 30 + x = 180
60 + x = 180
x = 120
Figure 2: 104 + 22 + x = 180
126 + x = 180
x = 54
Figure 3:
part 1: 154 + z = 180
z = 26
part 2: 90 + 26 + x = 180
116 + x = 180
x = 64
Perimeter:
p = 2b + 2h = 68
b = 4h - 6 (per problem statement)
substituting for b in the perimeter equation:
p = 2(4h - 6) + 2h = 68
(2)(4h) - (2)(6) + 2h = 68
8h - 12 + 2h = 68
10h - 12 = 68
10h = 68 + 12
10h = 80
h = 80/10
h = 8
b = 4(8) - 6 = 32 - 6 = 26
p = 2(26) + 2(8)
p = 52 + 16 = 68 . . . [OK]
b = 26 cm
h = 8 cm
x=5 is the answer thank you
