Please answer this!! (In your own words.) The best answer gets brainliest! Find the area:

Wittaler [7]

Answer:

97.5 sq. ft.

Step-by-step explanation:

Im presuming the question asks to find area of the shaded region.

First of all, the total figure is a rectangle. We can write an expression(in words) for the shaded area.

Shaded Area = Area of Rectangle - Area of Small Triangle(White) - Area of Large Triangle(White)

Now, we find respective areas.

Area of rectangle:

length * width = (5+10) * (12) = 15 * 12 = 180

Area of Small Triangle (white):

A = (1/2) * base * height = (1/2) * 5 * (12-3) = (1/2) * 5 * 9 = 22.5

Area of Large Triangle (white):

A = (1/2) * base * height = (1/2) * 10 * (12) = 60

Now, we find area of shaded region:

Shaded Area = Area of Rectangle - Area of Small Triangle(White) - Area of Large Triangle(White)

Shaded Area = 180 - 22.5 - 60 = 97.5 sq. ft.

i figure is formed by a square and a triangle. total area is 32.5 m. the area of the triangle is 75 m. what is the length of eac

Anni [7]

Answer:

The length of each side of the square is 5 meters

Step-by-step explanation:

The correct question is

A figure is formed by a square and a triangle. total area is 32.5 m^2. the area of the triangle is 7.5 m^2. what is the length of each side of the square?

we know that

The total area of the figure is equal to the area of triangle plus the area of square

The area of square is equal to the area f the figure minus the area of triangle

Let

A ----area of the square

$A=32.5-7.5=25\ m^2$

Find the length side of the square

Remember that the area of the square is

$A=b^2$

where

b is the length side of the square

substitute

$25=b^2$

square root both sides

$b=5\ m$

therefore

The length of each side of the square is 5 meters

The figures are similar. The area of one figure is given. Find the area of the other figure to the nearest whole number.

Akimi4 [234]

Answer: Option b.

Step-by-step explanation:

First, you need to calculate the ratio of the area. This is:

$ratio=(\frac{64}{28})^2\\\\ratio=\frac{256}{49}$

You know that the area of the smaller trapezoid is 771 m², then you can set up the following proportion, where "x" is the area of the larger trapezoid. Then you have:

$\frac{256}{49}=\frac{x}{771}$

Now you must solve for "x". Therefore, you get that the area of the larger trapezoid is:

$x=(771)(\frac{256}{49})\\\\x=4,028m^2$
