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
Answer:
The area is 217cm
Step-by-step explanation:
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

-4x+y=6
-5x-y=21
--------------
-9x=27
x=27/-9
x=-3
-5(-3)-y=21
15-y=21
y=15-21
y=-6
The answer is c.
Since a^2+b^2=c^2, b^2=c^2-a^2 thus,
16=4-b^2= srt. of 12
