\sf{3. \ \ Given : \dfrac{2}{3} - \dfrac{5}{4} + \dfrac{7}{2}}

Let us solve the first two fractions : The LCM of 3 and 4 is 12

\sf{\implies \dfrac{4(2) - 5(3)}{12} + \dfrac{7}{2}}

\sf{\implies \dfrac{8 - 15}{12} + \dfrac{7}{2}}

\sf{\implies \dfrac{-7}{12} + \dfrac{7}{2}}

LCM of 2 and 12 is 12

\sf{\implies \dfrac{-7 + 7(6) }{12}}

\sf{\implies \dfrac{-7 + 42}{12}}

\sf{\implies \dfrac{35}{12}}

\sf{\implies 2 +\dfrac{11}{12}}

\sf{\implies 2 \dfrac{11}{12}}

---------------------------------------------------------------------------------------

\sf{4. \ \ Given : \dfrac{(2 - 7)^2 + 5}{3}}

\sf{\implies \dfrac{(-5)^2 + 5}{3}}

\sf{\implies \dfrac{25 + 5}{3}}

\sf{\implies \dfrac{30}{3}}

\sf{\implies 10}

Answer:

51 cm^2

Step-by-step explanation:

To find the area excluding the shaded triangle, first find the area of the whole figure:

12 x 6 = 72cm^2

Now, find the area of the triangle:

(7 x 6) / 2

42/2

21cm^2

Lastly, subtract the shaded area from the whole:

72 - 21 = 51 cm^2
