Triangle

Area = 1/2 b * h

Area = 1/2*15 * 9 = 1/2 * 135 = 67.5

Rectangle

Area = b * h

Area = 15 * 4

Area = 60

Trapezoid

Area = (1/2) * (b1 + b2)* h

Area = (1/2) * (15 + 18) * 4

Area = 1/2 * 33 * 4

Area = 66

Total Area

Total Area = 66 + 60 + 67.5 = 193.5 Answer

Multiply or divide as indicated <br> b^3 x b^-3

Andru [333]

The domain: $b\neq0$

Method 1.

$Use\ a^n\cdot a^m=a^{n+m}\\\\b^3\cdot b^{-3}=b^{3+(-3)}=b^{3-3}=b^0=1$

Method 2.

$Use\ a^{-n}=\dfrac{1}{a^n}\\\\b^3\cdot b^{-3}=b^3\cdot\dfrac{1}{b^3}=\dfrac{b^3}{b^3}=1$
