A=2(LW+LH+WH)

A=2((7/8)(1/3)+(7/8)(2/5)+(1/3)(2/5))

A=2(7/24+14/40+2/15)

A=14/24+28/40+4/15

A=7/14+7/10+4/15 210

A=(105+147+56)/210

A=308/210

A=(210+98)/210

A=1 98/210

A=1 7/15

Answer:

$270.3\ ft$

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

In the right triangle ADE

Find the value of h1

See the attached figure

h1=AD

$tan(25\°)=\frac{h_1}{180}$

Solve for h1

$h_1=(180)tan(25\°)\\h_1=83.94\ ft$

step 2

In the right triangle ABC

Find the value of h2

See the attached figure

h2=BC

$tan(46\°)=\frac{h_2}{180}$

Solve for h2

$h_2=(180)tan(46\°)\\h_2=186.40\ ft$

step 3

Find the height of the neighboring building

we know that

The height of the neighboring building is equal to

$h=h_1+h_2$

substitute the values

$h=83.94+186.40=270.34\ ft$

Round to the nearest tenth of a foot

$h=270.3\ ft$
