**Reiny**, Monday, December 28, 2009 at 9:01pmyou have 2 similar triangles

the ratio of the numerical values of corresponding sides of the scale model to the actual garden is 2:1

Since the side in the scale model is 19.7 cm, the side in the garden would have to be 9.85 or 9.9 m.

(actually we could have just used the cosine law to find the third side of the garden

x^2 = 7^2 + 9^2 - 2(7)(9)cos 75º

x^2 = 97.3888

x = √97.3888 = 9.87 or 9.9 m )
