Answer:
217 sq cm
Step-by-step explanation:
to find the area of the blue portion you can find the area of the entire rectangle and subtract from it the area of the triangle
Area(rectangle) = 21 x 11
A = 231
Area(triangle) = 4(7)÷2
A = 14
Area(blue) = 231 - 14 = 217
The area is 217cm
area of triagle:
4x7 = 28
28/2 = 14
area of rectangle:
11x21 = 231
Since the triangle is inside the blue you subtract its area from the blue's area.
231-14 = 217
