Answer:
step 1: x+50+4x=90
the angle of a right-angled triangle is 90 degrees, therefore if we add everything together ,we could work out what x is.
step 2: x+50+4x=90
x+4x=50
5x=50
x=10
then you solve the equation, x is 10
Area of rectangle = 6 x 6 = 36 centimeters squared
Area of triangle = 1/2 x 6 x 6 = 18 centimeters squared
Total area = 36 + 18 = 54 centimeters squared.

A mixed number has a part that is whole and a part that is a friction.
For example:
3 1/2 and 3 2/3
3 1/2 * 3 1/4 = 7/2 * 13/4 = 91/8 = 11 3/8
9 < 11 3/8 < 12
