The area of a rectangle in 24 square units. a diagonal drawn from one corner to another divides the rectangle into two right triangles. what is the area of the shaded triangle?

Hello from MrBillDoesMath!

12

Discussion:

The two triangles shown are congruent by the SAS postulate so the area of a single triangle is one-half that of the rectangle.  That is,

Area = (1/2) * 24 = 12

Thank you,

MrB

(1/2) * 24 = 12

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
