Answer:
132 m²
Step-by-step explanation:
The rectangle is 20 m by 6 m.
Base of triangle: 20 m - 8 m - 6 m = 6 m
Height of triangle: 10 m - 6 m = 4 m
The triangle has a base of 6 m and a height of 4 m.
A = LW + bh/2
A = 20 m × 6 m + (6 m × 4 m)/2
A = 120 m² + 12 m²
A = 132 m²
Answer:
60
Step-by-step explanation:
Let the original number be x.
According to the question we can write as (2/3)x+20x
On rearranging x−(2/3)x=20
Now taking the L.C.M od 1 and 3 is 3
(3x−2x)/3=20
x/3=20
Again by transposing x=60
So the original number is 60
Answer: 11
Step-by-step explanation:
c(4)=-7+6(4-1)
c(4)= -7 + 6(3)
c(4)= -7 +18
c(4)= 11
I have no idea what to do. We have to do the same stuff too
