Find the base of a triangle with area of 42 square centimeters and a height of 12cm.

Area of a Triangle=1/2 Base* height
42=1/2* Base*12
Base=42*2/12
=7cm ANS.

  2. Area of a Triangle=1/2 Base* height
    42=1/2* Base*12
    Base=42*2/12
    =7cm ANS.

  3. The area of a triangle is A = a*b/2
    A=42 cm²
    b = 12 cm

    a = 2*A/b
    a= 2*42/12
    a=7

  4. Use the formula for the triangle:
    A=1/2bh
    42=1/2*b*12
    42=6b
    b=42/6
    b=7cm

    Plug it in to check it.

  5. I’d like to add that the reason the area of a triangle is 1/2 the base times the height is because every triangle is exactly one half of a parallelogram.
    In this case, a parallelogram 12 x 7 = 84 square centimeters.
