Parallelogram 25371

A parallelogram with a side length of 5 cm and a height to this side length of 4 cm has the same area as an isosceles triangle with a base length of 5 cm. What is the height of this triangle?

Correct answer:

h2 =  8 cm

Step-by-step explanation:

a=5 cm h1=4 cm b=5 cm  S1=a h1=5 4=20 cm2  S1=S2  S2 = 2b h2  h2=2 S1/b=2 20/5=8 cm
