What is the base of the trapezoid with an area of 150 a height of 10 and a base of 14?
slavikrds [6]
The formula for the area of a trapezoid is:

A= (a+b)/2*h

A=150
h=10
b=14
a=?

So we need to solve for a. Let's plug in the values that we do know...

A= (a+b)/2*h
150=(a+14)/2*10
150=(a/2+14/2)*10
150=(a/2+7)*10
Divide both sides by 10
15=a/2+7
subtract 7 from both sides
8=a/2
multiply both sides by 2
16=a

The other base is 16

Anvisha [2.4K]
Start by taking the information we know, and write equations to represent the realationships:

1) "1/8 lbs less flour to make bread than to make cookies"         
     b=c-\frac{1}{8}

2) "1/4 lb more flour to make cookies than to make brownies:
     c=w+\frac{1}{4}

3) "she used 1/2 lb of flour ro make bread"
    b = \frac{1}{2}

From here you can solve for w using back substitution.
