The area of the triangle extension is 12, because the total side length it is on is 18, and the segments to the sides of the triangle are 6 each, meaning 18-12=6, the height of the triangle. The base is given as 4, so 1/2(4x6)=24/2=12.

Add this to the area of the rectangle, 9x18=162, and 162+12=174.

The area is 174.

What is the value for B, after the equation cap a equals start fraction three over seven end fraction left parenthesis cap b min
r-ruslan [8.4K]

<u><em>Answer:</em></u>

B = \frac{7}{3}A + 25

<u><em>Explanation:</em></u>

<u>The given equation is:</u>

A = \frac{3}{7} (B-25)

To get the value of B, we will need to isolate it on one side of the equation

<u>This is done as follows:</u>

A = \frac{3}{7} (B-25)  

<u>1- Multiply both sides by \frac{7}{3} to get rid of the fraction:</u>

\frac{7}{3}A = B - 25

<u>2- Add 25 to both sides of the equation:</u>

\frac{7}{3} A + 25 = B

Based on the above:

B = \frac{7}{3}A + 25

Hope this helps :)
