What is the area of this figure

Help please

Step-by-step explanation:

A you see here, we have 3 different shapes. a Triangle, a big and small rectangle. Lets start with the triangle.

between the 8 in's, theres a gap. 5+4=9,

9+8+8=25. we have the length of the triangle.

9*25 divided by 2= 112.5. thats are area of the triangle.

for the bigger rectangle, 20*9=180, the area of the rectangle, and the smaller rectangle at the bottom is 16.

Now we add:

112.5+180+16=308.5  

hope this helps!

step-by-step explanation:

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
