Answer:
<em>9%</em>
Step-by-step explanation:
Original rectangle: 100 cm by 200 cm
Original area: 100 cm * 200 cm = 20,000 cm^2
Reduced by 70%, the measures are now 30% of they they were.
30% of 100 cm = 30 cm
30% of 200 cm = 60 cm
New area: 30 cm * 60 cm = 1800 cm^3
New area equals what percent of original area?
1800/20,000 * 100 = 9%
27 cm^2
Step-by-step explanation:
Area of a rectangle = Length×Width
4.5 cm × 6 cm = 27 cm^2
The slope of parallel lines are always; Equal
<h3>Slope of a line</h3>
The formula for slope intercept form of a line is;
y = mx + c
Where;
- m is slope
- c is y-intercept
Now, when two lines are perpendicular to each other, it means their slopes will be; m and -1/m.
Whereas when two lines are parallel to each other, both of their slopes will be m which means they are always equal to each other.
