Question

Find the area and the perimeter. Use 3.14. Round your answer to the nearest tenth. Need help ASAP!!

Answer 1

The formula of an area of trapezoid:

$A=\dfrac{base_1+base_2}{2}\cdot height$

We have:

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

Substitute:

$A=\dfrac{7+3}{2}\cdot3=\dfrac{10}{2}\cdot3=5\cdot3=15\ ft^2$

The perimeter:

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