Question

anonymous · Answer

The area of a right triangle is 30mm squared. The height is 12mm. Find the perimetier

anonymous · Answer

Area = 1/2 (b*h)
30 = 1/2 (b * 12)
60 = b*12
b = 5
5^2+ 12^2 = 169
c = 13
perimeter = 12+5+13 = 30

S=AB*BC/2
30=12*BC/2 
multiply both sides by 2
60=12*BC
