The height of a triangle is one quarter it's base, if the area of the triangle is 98cm² find the base and height.

Answer 1

bh/2=area

b*b/8=98

8b^2/8=784

b^2=784

b=28

h=7

Answer 2

h = b/4

A = (1/2)bh = (1/2)b(b/4) = b²/8 = 98

b² = 784 , b = √784 , b = 28 , h = 7

Check: A = (1/2)·28·7 = 98 √
