Hyopentuse = 9√2, therefore:
Base = 9  + 9  = 18 m
Height = 9 m

Area of the top triangle  = 1/2 (9) (18)  = 81 m²
Area of the bottom triangle = 1/2(6)(18) = 54 m²
Tota area  = 81 + 54 = 135 m²

Please help!!!<br> Which expression is equivalent to (3m^-1n^2)^4/(2m^-2n)^3
Elza [17]
\text{Use:}\\\\(a\cdot b)^n=a^nb^n\\\\(a^n)^m=a^{n\cdot m}\\\\\dfrac{a^n}{a^m}=a^{n-m}

\dfrac{(3m^{-1}n^2)^4}{(2m^{-2}n)^3}=\dfrac{3^4(m^{-1})^4(n^2)^4}{2^3(m^{-2})^3n^3}=\dfrac{81m^{-4}n^8}{8m^{-6}n^3}\\\\=10.125m^{-4-(-6)}n^{8-3}=10.125m^2n^5
