AVprozaik [17]

Answer:

$Length= 429 feet\\Width=143feet$

Step-by-step explanation:

Perimeter of the rectangle= 1144 feet

Length=3*Width

L=3*W

Perimeter of rectangle:

$2(Length+Width)\\\\ 1144=2(3W+W)\\\\ 1144/2=3W+W\\\\ 572=4W\\\\ W=572/4\\\\ W= 143 feet\\\\Width=143 feet\\\\Length=3*143=429 feet\\\\$

The Dimension of the rectangle is :

$Length= 429 feet\\Width=143feet$

Answer:

Yes;Each side of triangle PQR is the same length as the corresponding side of triangle STU

Step-by-step explanation:

You can observe the sides of both triangles to see if this property holds

Lets check the length of AB

A(0,3) and B(0,-1)

$AB=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\\\\\\\AB=\sqrt{(0-0)^2+(-1-3)^2} \\\\\\\\AB=\sqrt{0^2+-4^2} \\\\\\AB=\sqrt{16} =4units$

Now check the length of the corresponding side DE

D(1,2) and E(1,-2)

$DE=\sqrt{(1-1)^2+(-2-2)^2} \\\\\\DE=\sqrt{0^2+-4^2} \\\\\\DE=\sqrt{16} =4units$

The side AB has the same length as side DE.This is also true for the remaining corresponding sides.
