Answer:
110 cm^2
Step-by-step explanation:
The first thing that you need to do is find the area of triangle AFE. The area of a triangle is always base*height/2. So in this case, that would be 10*6 divided by 2, which is 30 cm. Next, you will need to know the area of triangle ECB. Using that same formula, you will get 8*10/2, which is 40 cm. Finally, you will need to find the area of the whole rectangle. The area of a rectangle is always the length times the width. In this case, you would have 10*18, which is 180 cm. To get your final answer, you need to subtract the areas of the unshaded area from the whole area. That would be 180-(30+40), which is 110 cm. I hope this helped!

Answer:
{15 - {(25 x 2.4) + 7}}- (3 x 2) = -16
Step-by-step explanation:
15 - 25 x 2.4 + 7 - 3 x 2= -16 is the given equation.
Now by the rule of BODMAS:
here B = Bracket, O means Of, D means Divide, M means Multiplication , A means Addition and S means Subtraction.
So, according to this order start putting brackets.
first operation is multiplication, second is addition and then subtraction.
⇒ 15 - 25 x 2.4 + 7 - 3 x 2 = {15 - {(25 x 2.4) + 7}}- (3 x 2)
Hence, {15 - {(25 x 2.4) + 7}}- (3 x 2) = -16
