3.)
Area of Shape= Area of rectangle + area of triangle
[tex] = fxb + \frac{1}{2} \: x \: base \: x \: leish \\ = 9x6 + \frac{1}{2} \: \times 6 \times {6}^{3} \\ = 54 + 18 \\ = 72 {cm}^{2} [/tex]
4.)
Area of Shape= Area of Triangle + Area of Hemisphere
[tex] = \frac{1}{2} \times base \times h + 2 {m}^{2} \\ = \frac{1}{2} \times 4 \times 7 + 2 \times \frac{22}{7} \times 4 \times 4 \\ = 28 + 2 \times 3.14 \times 16 \\ = 28 + 6.28 \times 16 \\ = 28 + 160.48 \\ = 128.48 {cm}^{2} [/tex]
5.)
Are os Shape + Area of Rectangle + Area of Rectangle
[tex] = f \: xb \: + fxb \\ = 5 \times 7 + 5 \times 13 \\ = 35 + 65 \\ = 100 {m}^{2} [/tex]
