Answer: 294N/84cm² reduces to 7N/2cm²
Step-by-step explanation: Get the area of the triangle A= bh/2
A = 14(12)/2 . Area = 84cm² Remember to keep the units cm×cm= cm²
Use the given value for the Force, 294N and substitute them in the formula given: pressure = force/area
294/84 = 7/2 Newtons per square centimeter.
(divide numerator and denominator by LCM, 7 to simplify) .
7/2 = 3.5
That converts to 35000 Paschal But that's more of a Physics answer, probably more than you need here!
