Atriangle has a height of 11.6 centimeters and an area of 54.52 square centimeters. what is its length?

(54.52(2)) / 11.6= 109.04/ 11.6= 9.4

The height is 9.4cm

Hope this helps!

A = BH/2   --- Equation for triangle area
54.52cm² = B(11.6cm)/2   --- Substitute the numbers in for Area and Height
   *2                     *2   --- Multiply both sides by 2

109.04cm² = (11.6cm)B   
/11.6cm            /11.6 cm   --- Divide both sides by 11.6cm to isolate B

9.4cm = B    ---Length is equal to 9.4 cm.
