Question

Find the area of the trapezoid.

Answer 1

the rectangular area is l*w
the two triangles are each base * height
can you do it from here?

Answer 2

left triangle you can find by tan
\[\LARGE \tan 45^{\circ}=\frac 5x\]
\[\LARGE 1=\frac5x \]
\[\LARGE x=5\]
so you have its area

\[\LARGE A=\frac12\cdot 5\cdot 5 \]
\[\LARGE A=\frac{25}{2}\]
since you have TWO triangles and they're the same
2A
A=2(25)/2
A=25

So Area of Two triangles together is 25cm^2
now rectangle is easy to find :)

Answer 3

Area of Rectangle is A=l*w
A=7*5
A=?


once you have that...
sum it with 25cm^2
and you'll have the Area of trapezoid :)

Answer 4

area =(17+7)*5/2

Answer 5

area=24*5/2 =12*5=60
