A rectangular field is eight times as long as it is wide. If the perimeter of the field is 900 feet, what are the dimensions of
Bas_tet [7]

Answer:

400 feet long

50 feet wide

Step-by-step explanation:

Length = l

Width = w

2l + 2w = 900

l = 8w

Plug the l from the bottom equation into the top equation

2 x 8w+ 2w = 900

16w = 900

Divide both sides by 16

16w/16 = 900/16

w = 50

The width is 50 feet

Now plug the new w into one of the original equations; we'll use the bottom one

l = 8(50)

l = 400

what is the height of a trapezoid with one base equal to 20m, the other base equal to 7m, and an area of 135m^2
german

Answer:

<h2>The height is 10 m</h2>

Step-by-step explanation:

Area of a trapezoid is given by

<h3>A =  \frac{1}{2} (a + b)h</h3>

where

a and b are the bases

h is the height

From the question

A = 135 m²

a = 20m

b = 7 m

Substitute the values into the above formula and solve for the height

That's

<h3>135  = \frac{1}{2} (20 + 7)h \\ 135 =  \frac{1}{2}  \times 27h \\ 135 \times 2 =  2 \times \frac{1}{2}  \times 27h \\ 270 = 27h</h3>

<u>Divide both sides by 27</u>

That's

<h3>\frac{27h}{27}  =  \frac{270}{27}</h3>

We have the final answer as

<h3>10 m</h3>

Hope this helps you
