Answer:

  72 square units

Step-by-step explanation:

The figure shown has a uniform horizontal cross section, so is equivalent to a rectangle with length 12 and height 6. Its area is given by the rectangle formula:

  A = LW

  A = (12)(6) = 72 . . . . square units

__

<em>Additional comment</em>

Essentially, the semicircle removed from the left side is tacked onto the right side. The rectangle area is unchanged by that.

Il perimetro di un rettangolo è 126 cm. La base è i tre quarti dell'altezza. Mi potreste dire come procedere? ​
Oksana_A [137]

Answer:

w = 36 cm

L = 27 cm

Step-by-step explanation:

I am translating and I see that perimeter of rectangle is 126 cm and the base (assuming Length) is (3/4) the height.

P = 2(l+w)

126=2((\frac{3}{4} w)+w)

Divide both sides by 2, so you get

(3/4)w+(4/4)w=(126/2)

(7w/4)=63

Multiply both sides by 4,

7w=252, then divide both side by 7,

w = 36, Width is 36 cm, so Length is (3/4), which is L = 27 cm
