Question

What is the area in square millimeters of the triangle outlined on the origami​ figure?

Answer 1

Given

• base =8 cm
• height = 1.58 cm

Area of triangle ${\red{\frac{1}{2}}} \blue\times \: Base×height$

= $\huge{\green{\frac{1}{2}}}\times \:\orange{ 8\times 1.58}$

= $\huge{\purple{\frac{12.64}{2}}}$

$\red{\underline{\boxed{\bf{=6.32}}}}$

Now,

• To convert it into square millilitres we have to multiply it with 100

⠀⠀⠀⠀⠀⠀⠀⠀⠀6.32 × 100

⠀⠀⠀⠀⠀⠀⠀⠀⠀= 632mm²
