Find the area of this shape

cestrela7 [59]

Answer:

28ft^2

Step-by-step explanation:

you only need 2 things to find the area of the triangle, base and height. The formula for finding the area is 1/2(base x height)

if we plug the numbers we are given into the formula we find

1/2(7x8)

1/2(56)

we find that the area of this triangle is 28ft^2

What is the area of a rectangle with vertices at (0, −4) , (−1, −3) , (2, 0) , and (3, −1) ? Enter your answer in the box

Bad White [126]

We are given vertices of a rectangle (0, −4) , (−1, −3) , (2, 0) , and (3, −1).

Length is the distance between (0, −4) and (−1, −3) points.

Width is distance between (−1, −3) and (2, 0) points.

<u>Computing length:</u>

$\mathrm{Compute\:the\:distance\:between\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$

$=\sqrt{\left(-1-0\right)^2+\left(-3-\left(-4\right)\right)^2}$

$=\sqrt{2}$

<u>Computing Width :</u>

$\mathrm{The\:distance\:between\:}\left(-1,\:-3\right)\mathrm{\:and\:}\left(2,\:0\right)\mathrm{\:is\:}$

$=\sqrt{\left(2-\left(-1\right)\right)^2+\left(0-\left(-3\right)\right)^2}$

$=3\sqrt{2}$

<h3>Area of the rectangle = Length × Width </h3>

= $\sqrt{2} \times 3\sqrt{2} = 3 \times 2 = 6 \ squares \ units.$ .
