Answer:
35cm² or 35 sq cm
Step-by-step explanation:
Formula for area in a triangle: [tex]\frac{1}{2} \\[/tex] (B × H) or h[tex]\frac{b}{2}[/tex]
1st formula:
A= [tex]\frac{1}{2} \\[/tex] (B × H)
A= [tex]\frac{1}{2} \\[/tex] (10 × 7)
A=[tex]\frac{1}{2} \\[/tex] (70)
A= 35cm²
2nd formula:
A= h[tex]\frac{b}{2}[/tex]
A= 10[tex]\frac{7}{2}[/tex]
A= 10 × 3.5
A= 35cm²
