Answer:
45 centimeters squared (45 square centimeters - same thing)
Explanation:
First we need the area of each shape
To find the area of a right triangle we multiply the length of the legs and then divide by 2 - ab/2
Triangle 1: 6 centimeters squared
Triangle 2: 9 centimeters squared
To find the area of a rectangle you multiply the length by the width - lw
Rectangle: 30 centimeters squared
Now we add the values together:
6 + 9 + 30 = 45 centimeters squared
That is my answer, if you need anything else or more clarification I will edit this :)
