Answer:
36cm^2
Step-by-step explanation:
Since the square was enlarged by a scale factor 2, sides of the old square = 12/2
= 6
Area of the original quare = L x L
= 6 x 6
= 36cm^2
To solve this
problem, we must remember that the sum of interior angle of a polygon is:
Sum of
interior angles = (n – 2) * 180˚
So, we can say
that:
Sum of
interior angles = angle A + angle B + angle C + angle D = (4 – 2) * 180˚
Where,
angle C + angle
D = 110 + 70 = 180˚
Therefore
substituting this value:
angle A + angle
B + 180˚ = 2 * 108˚
angle A + angle
B = 360˚ - 180˚
angle A + angle
B = 180˚ (answer)
Hence we can
also conclude that,
<span>angle A + angle
B = angle C + angle D</span>
Answer: 175%
Step-by-step explanation:
7/4 x 100 = 1.75
Answer:
8.5cm
Step-by-step explanation:
convert 3.4metres to cm that is by multiplying by 100
3.4×100=340cm
1rep 40
?rep 340
that is 340/40
=8.5cm
Answer:
The area of the figure is 36.57.
Step-by-step explanation:
- find the area of the rectangle
6 x 4 = 24
- find area of the half circle
radius = 2
12.57
- add them up
24+12.75= 36.57
