Answer:
2
Step-by-step explanation:
The area of a triangle is equivalent to its length multiplied by its width.
In this example, one way we can look at this is to make everything in terms of two. First, we know that
We can establish that last line because x^((y)^(z)) = x^(y*z), as is stated in exponent rules. Therefore, our area is
=3m+6m+2m
=(3m+6m+2m)
Answer is= 11m
Answer:
27 minutes
Step-by-step explanation:
Given that:
It takes 16 minutes for 9 people to paint 8 walls.
i.e
16 minutes ------------ 9 people ---------- 8 walls
How many minutes does it take 4 people to paint 6 walls?
let the number of minutes be (m). NOW;
(m) minutes ------------ 4 people ------------ 6 walls
If it takes 16 minutes for 9 people to paint 8 walls.
∴ For 1 person to paint 8 walls; it will take 16 minutes × 9 = 144 minutes
So, to determine the number of minutes it will take 1 person to paint 6 walls; we have;
6 walls =
6 walls × 144 minutes = 8 walls × (m)
(m) =
m = 108 minutes
So, it will take 108 minutes for one person to paint 6 walls.
For 4 people now; we have
m =
m= 27 minutes
∴ it will take 27 minutes for 4 people to paint 6 walls
