Respuesta :

the equation is
.5height(top+bottom)
so...
2.5*13= 32.5 units squared

Answer:

The area of the doghouse is [tex]32.5\ ft^{2}[/tex]

Step-by-step explanation:

we know that

The area of trapezoid is equal to

[tex]A=\frac{1}{2}(b1+b2)h[/tex]

where

b1,b2 are the parallel bases of trapezoid

h is the height of trapezoid

in this problem we have

[tex]b1=5\ ft[/tex]

[tex]b2=5+3=8\ ft[/tex]

[tex]h=5\ ft[/tex]

substitute

[tex]A=\frac{1}{2}(5+8)5=32.5\ ft^{2}[/tex]
