Answer:
Its 156
Step-by-step explanation:
36 times 2=72 42 times 2= 84 84 + 72 = 156
19.941 would round to 20 when rounded to the nearest one.
If 1km is equal to 0.6mi then 5km is equal to 3mi
Y=4x+5.
4 is the gradient
+5 is the y intercept
Let's say that BC is x, so that AB is 4x, and AE = y.
The shaded area then is represented by 4xy/2 = 2xy.
The total area is represented by (4x+x)*y = 5xy.
The fraction of these is 2xy/5xy = 2/5.
