Chapter 10 - Area - 10-2 Areas of Trapezoids, Rhombuses, and Kites - Got It?: 1

Answer

The area of the trapezoid is $94.5cm^2$.

Work Step by Step

The formula for the area of the trapezoid is: $A=1/2h(b1+b2)$ $b1=$ the top base of the trapezoid $b2=$ the bottom base of the trapezoid The $height$ in this problem is $7$ $Base 1$ in this problem is $12$ $Base 2 $ in this problem is $15$ We just need to plug in the numbers into the formula. $A=1/2 (7)(7+15)$ $A=1/2(7)(27)$ $A=94.5$ The area of the trapezoid is $94.5cm^2$
