Given: The area of the bridge ramp = 48a+120b+160c square units
a=12, b=21, and c=30
The area where the bridge will be built = 9000 square units
To find: A. The dimensions of the bridge
B. Whether the bridge fit in this area
Solution:
A. First, we need to find the dimensions of the bridge ramp by substituting the values of a, b and c which are given as a=12, b=21, and c=30.
Hence, putting the values of a, b and c, we get
48 × 12 = 576 units
120 × 21 = 2520 units
160 × 30 = 4800 units
Hence the dimensions of the bridge are 576 units, 2520 units and 4800 units.
B. The area of the bridge ramp = (576 + 2520 + 4800) square units
= 7896 square units
And the area where the bridge will be built is 9000 square units.
Since 7896<9000, so the bridge will definitely fit in the given area.
Answer: 576 units, 2520 units and 4800 units
Yes
