Answer:
10
4
Step-by-step explanation:
Purple: This makes two trapezoids. A=(a+b)/2 times h
1st = (4+1)/2 x 1 = 2.5
2nd = (4+1)/2 x 3 = 5/2 x 3 = 2.5x3=7.5
Total = 2.5+7.5=10
Green: if you draw a line down the center, you can divide these into two more manageable triangles. A=1/2bh
1st = 1/2x2x2 = 2
2nd = 1/2x2x2 = 2
Total = 2+2=4
Answer:
5
Step-by-step explanation:
<em>~Hello fellow army~</em>
For this, all you have to do is subtract 9 and 4.
Which is 5 cm.
<u>Final answer</u>
5 cm
<span>2/7m-1/7=3/14
make the denominators equal and to this just multiply the denominators of the first two equations by 2 but you have to multiply the numerators too and by the same value
4/14m - 2/14 = 3/14
with the denominators equal, you can delete them
4m-2=3
4m=3+2
4m=5
m=5/4</span>
Answer:
72 inches²
Step-by-step explanation:
Let
be equal to the width of the rectangle.
Let
be equal to the length of the rectangle.

Plug in 12 inches as the length

Therefore, the width of the rectangle is 6 inches.

Plug in 12 inches as the length and 6 inches as the width.

Therefore, the area of the rectangle is 72 inches².
I hope this helps!
