Answer:

Triangle: 77

Parallelogram: 198

Total: 275

Step-by-step explanation:

The area of a triangle is one half the base times the height.

$A_{T}=\frac{1}{2}bh=\frac{1}{2}(22)(7)=77$

The area of a parallelogram is base times height.

$A_{P}=bh=(22)(9)=198$

The total area is the sum.

77+198=275

Answer:

<h2>Area of triangle = 1/2 b×h</h2><h2>1/2×22×7 = 77cm^2</h2>

<h2>Area of parallelogram = b×h</h2><h2>Area = 22×9</h2><h2>= 198cm^2</h2>

<h2>Total area of composite figure</h2><h2>77cm^2 + 198cm^2</h2><h2>= 275cm^2</h2>

Plz tell about congruent and similar triangles

prohojiy [21]

Similar: If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion.

____________________________________________________________

Congruent: SAS stands for "side, angle, side" and means that we have two triangles where we know two sides and the included angle are equal. If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are congruent.

Address the following question: In a different city, if the landfill volume required per year is 300,000 m3, and the average fil

Brilliant_brown [7]

Answer:

A=20,000 m2 per year

Step-by-step explanation:

we have that Volume (V) =300,000 m3, so V=A*h, where A=area (m2) and h=15m

V=A*h ⇒ 300,000m3=A*15m ⇒ A=300,000m3/15m ⇒ A=20,000 m2

Would do anything for the answer to this question

olga_2 [115]

<u>Given</u>:

The length of the entire rectangle is 10x + 7.

The width of the entire rectangle is 6x.

The length of the unshaded rectangle is 4x - 5.

The width of the unshaded rectangle is 2x.

We need to determine the area of the shaded region of the rectangle.

<u>Area of the entire rectangle:</u>

The area of the entire rectangle can be determined using the formula,

$A=length \times width$

Substituting the values, we have;

$A_1=(10x+7)(6x)$

$A_1=60x^2+42x$

Thus, the area of the entire rectangle is 60x² + 42x

<u>Area of the unshaded rectangle:</u>

The area of the unshaded rectangle can be determined using the formula,

$A=length \times width$

Substituting the values, we have;

$A_2=(4x-5)(2x)$

$A_2=8x^2-10x$

Thus, the area of the unshaded rectangle is 8x² - 10x

<u>Area of the shaded region of the rectangle:</u>

The area of the shaded region of the rectangle can be determined by subtracting the area of the entire rectangle by the area of the unshaded rectangle.

Thus, we have;

$A=A_1-A_2$
