Answer:
391.2cm²
Step-by-step explanation:
Triangle = 1/2bh*2=1/2(4)(6.9)(2)=27.6 for each end triangle.
14*8=112 for each rectangular side.
112+112+112+27.6+27.6=391.2cm²
Answer:
100, 102, 104
Step-by-step explanation:
Hi there!
Let <em>x</em> be equal to the first number in the set of the three consecutive even numbers.
We're given that the sum of three consecutive even numbers is 306.
Because <em>x</em> is the first number, the next would be <em>x</em>+2, and then <em>x</em>+4. These are our even numbers.
We can now set up an equation:

Combine like terms:

Therefore, the first number in the set of 3 numbers is 100.
The next two even numbers after 100 is 102 and 104.
Therefore, the three numbers are 100, 102 and 104.
I hope this helps!
Answer:
Yes it is.
Step-by-step explanation:
Either way you are going to get the same answer, because it is addition.
Answer:
The formula to find the area of a rectangle is l * w
Answer:
Area for rectangle = B*H
Area for triangle = B*H/2
total area = area of triangle + area of rectangle
A of rectangle = 17 * 22 = 374 cm²
Triangle height is not giving so we take 22-10 = 12 cm for the height so
A of triangle = 12*19/2 = 114 cm²
total A = 114 + 374 = 488 cm²
