A flower bed is in the shape of a triangle with one side twice the length of the shortest side, and the third side is 2525 feet

guapka [62]

X + 2x + (x+ 2525) = 189189
4x = 186664
x = 4666
2x = 9332
x+ 2525 = 4919

On a coordinate plane, parallelograms A B C D and E F G H are shown. Parallelogram A B C D has points (4, 2), (7, 2), (4, 6), (1

Fittoniya [83]

Answer:

The area of parallelogram ABCD is equal to the area of parallelogram EFGH.

Step-by-step explanation:

Given

Parallelogram ABCD

$A = (4,2)$

$B = (7,2)$

$C =(4,6)$

$D = (1,6)$

Parallelogram EFGH

$E =(-2,2)$

$F = (-5,2)$

$G = (-6,6)$

$H = (-3,6)$

Required

Compare the areas of both parallelograms

The area of a parallelogram is:

$Area =Base * Height$

So: To do this, we plot ABCD and EFGH on a grid, then we measure the base and the height of both.

See attachment 1 for ABCD

In (1), we have:

$Base = 3\ units$

$Height = 4\ units$

So, the area is:

$A_1 = 3 * 4$

$A_1 = 12$

See attachment 2 for EFGH

In (2), we have:

$Base = 3\ units$

$Height = 4\ units$

So, the area is:

$A_2 = 3 * 4$

$A_2 = 12$

<em>By comparison, they both have the same areas</em>
