Answer:
6 inches
Step-by-step explanation:
The formula for the area of a triangle is
b - base
h - height
the first step is to add the information that we know into the formula.
We know the area = 
and the height = 5 inches
if we had both the base and the height, the next step would be to multiply
b x h then half the answer to work out the area but as we already have the area (
) we need to work in reverse.
15 x 2 = 30
what is 5 multiplied by to get 30?
5 x ? = 30
30 ÷ 5 = 6
∴ the base = 6inches
to check if our answer is correct, we can place these numbers into the formula
A = 
A = 
(30 ÷ 2 = 15)
A = 15

Answer:
It will take a total of 2.73 hours if they worked together
Step-by-step explanation:
Here, we are seeking to calculate the joint rate.
Let the amount of work to be done is say x
Seth’s rate will be x/6 , while violet’s rate will be x/5
Their joint rate will be ;
x/6 + x/5 = 11x/30
The time it will take them to build the house together will be equal to the amount of work divided by the joint rate.
That will be x divided by 11x/30
= x * 30/11x
= 30/11 hours which is Approximately 2.73 hours
