Question

the scale drawing uses a scale of 1 unit : 9 feet. 4 units 4 units 8 units which of the following accurately reproduces the drawing using a scale of 1 unit : 6 feet? 8 units 8 units 5 units 5 units 12 units 8 units 6 units 6 units 10 units 10 units 9 units 12 units

Explanation:

Step1: Find actual lengths

The original scale is 1 unit : 9 feet. Sides are 4 units, 4 units and 6 units. So actual lengths are $4\times9 = 36$ feet, $4\times9=36$ feet and $6\times9 = 54$ feet.

Step2: Calculate new units

The new scale is 1 unit : 6 feet. So new number of units for sides are $\frac{36}{6}=6$ units, $\frac{36}{6}=6$ units and $\frac{54}{6}=9$ units.

Answer:

The triangle with sides 6 units, 6 units and 9 units.
