Question

If the area of a triangle with base 12 cm is equal to the area of a square with side 12 cm, the altitude of the triangle will be

• A. 12 cm
• B. 24 cm
• C. 18 cm
• D. 36 m

Answer 1

Answer:

B. 24 cm

Area of square $= (12)^2 = 144 cm^2$

Area of triangle $=\frac{1}{2}\times{base}\times{height}$

$144=\frac{1}{2}\times{12}\times{height}$

$144=6height$

$height=\frac{144}{6}$

$=24cm$
