The formula of an area of trapezoid:


A=(base_1+base_2)/(2)\cdot height

We have:


base_1=3ft+4ft=7ft\\\\base_2=3ft\\\\height=3ft

Substitute:


A=(7+3)/(2)\cdot3=(10)/(2)\cdot3=5\cdot3=15\ ft^2

The perimeter:


P=3+4+5+3+3=18\ ft

Find the area and the perimeter. Use 3.14. Round your answer to the nearest tenth-example-1
