Then there would be 9 girls and 23 boys
Step-by-step explanation:
Area of rectangle= lw
Divide the number 135 and 5. It is going to be 27. Then you multiply 27 times 4. Then you get your answer which is 108.
Proportion set up....
small 4 ? small
----- --------
big 5 135 big
Cross multiply 4x135= 540
and then divide 540/5= 108
Step 1: -4(3x-1) becomes -12x+4
step 2: -12x+4=12-8x
step 3: add 12x to both sides, 4=12+4x
step 4: subtract twelve from both sides -8=4x
step 5: divide by 4, x=-2

Explanation:
We're given the height in relation to base BC, so we need to find the length of this base. This is the same as finding the distance from B to C.
Turn to the distance formula
Coincidentally, the base and height are the same. This won't always be the case.
Now we can find the area of the triangle
The area of the triangle is 1 square unit.
See diagram below.
