Answer:
The sides of a triangular flower bed are 5m, 8m and 11m . the area of flower bed will be?
First, write the scale factor.
scaleactual=120
Next, write a ratio to represent the actual length of the side to the unknown scale length of the side.
scaleactual=l5.5
Then, write a proportion by setting the two ratios equal to one another. Meters is the only unit given. 120=l5.5meters
Next, cross multiply.
5.5l=20l=0.275 meters
Then, convert meters to centimeters.
0.275 meters×1001cmm=2.75 cm
The answer is 27.5 centimeters.
