1. Area of an Right triangle
Answer:
[tex]5cm^{2}[/tex]
Step-by-step explanation:
[tex]\frac{1}{2} (base)*(height)\\=\frac{1}{2} (5cm)*(2cm)\\=\frac{1}{2}(10cm^{2} ) \\=5cm^{2}[/tex]
2. Area of anTriangle
Answer:
[tex]9m^{2}[/tex]
Step-by-step explanation:
[tex]\frac{1}{2}(base)*(height)\\= \frac{1}{2} (6m)*(3m)\\=\frac{1}{2} (18m^{2})\\ =9m^{2}[/tex]
3. Area of a Parallelogram
Answer:
[tex]36cm^{2} \\[/tex]
Step-by-step explanation:
[tex]base x height\\=(9cm)*(4cm)\\=36cm^{2}[/tex]
4. Area of an Trapezoid
Answer:
[tex]81cm^{2} \\[/tex]
Step-by-step explanation:
[tex]\frac{a+b}{2}*height\\=\frac{6cm+12cm}{2}*9cm\\\\=\frac{18cm}{2}*9cm\\=9cm*9cm\\=81cm^{2}[/tex]
5. Area of an Trapezoid
Answer:
[tex]150cm^{2}[/tex]
Step-by-step explanation:
[tex]\frac{a+b}{2}*height\\\\=\frac{16cm+14cm}{2}*(10cm)\\=\frac{30cm}{2}*(10cm)\\ =15cm*10cm\\150cm^{2}[/tex]
