Answer:
Below in bold.
Step-by-step explanation:
Area = altitude * base
3. 6.2 * 6
= 37.2 cm^2.
4. 0.12 * 0.24
= 0.0288 m^2.
5. 32 * 0.4
= 12.8 m^2.
Well to find this line you want to know the slope and the y-intercept. So find the slope:
(y2-y1)/(x2-x1)
12-2 = 10
2-7 = -5
10/-5 = 2/-1
-2 is your slope
Now for y-intercept, find the point closest to the y-axis. That is the point (2,12), and if your slope is negative 2, that means that if you go up 4 and left 2, you should find the y-intercept:
12 + 4 = 16
16 is your y-intercept
So now lets write this out in an equation:
y = mx + b
m = slope
b = y-intercept
y = -2x + 16
there you go! hope this helps!
Answer:
c) 56 m²
Step-by-step explanation:
Area of the figure = area of triangle + area of rectangle
Rectangle:
length = 8 m
Width = 5 m
Area = length * width
= 8 *5
= 40 m²
Triangle:
base (b)= 4 m
height (h) = 8 m
= 2* 8
= 16 m²
Area of the figure = 40 + 16
= 56 m²
