how come i got false as my answer ?

Question

The formula for the area of a triangle is A= 1/2 bh, where b is the base of the triangle and h is the height of the triangle. What is the length of the base in the area is 32cm squared and the height is 4cm.

Answer 1

Hello, Rachel,

Since A = (1/2)*B*H,

put both the area and height into the equation to find the base, B.

32cm² = (1/2)*B*4cm

32cm² = 2*Bcm

B = 16 cm

What answer did you get that registered as "false?"

Answer 2

A = (1/2)bh

2A = bh

2A/h = b

2(32)/4 = b

b = 16 cm
