Answer to Question #187378 in Algebra for Natalya

Question

On a scale drawing of a park, a triangular area has side lengths 8cm, 15cm, and 17cm. If the triangular area of the actual park has a perimeter of 160m, what is the length of its shortest side?

Answer 1

Answer

Perimeter of the scaled drawing:

=8+15+17=40cm

40cm rep 160m

Therefore, scale=1:4 i.e.

40:160=

1:4

Thus using this scale, the scaled shortest length, 8cm , in actual field is

84=32m

Thus shortest length is 32 meters
