Find the perimeter and area. (plz help with the answer)
ikadub [295]

Hello!

PERIMETER:

To find the perimeter of the trapezoid, simply add all sides together.

15 + 5 + 9 + 5 = 34

The perimeter is \boxed{ \bf 34~units.}

____________________________________________________________

AREA:

A = \frac{1}{2} h(b_{1} + b_{2})

A = \frac{1}{2} 4(9 + 15)

A = \frac{1}{2} 4(24)

A = 2(24)

A = 48

The area of the trapezoid is \boxed{ \bf 48~units^2}
