This model represents the design of a bridge truss composed of congruent triangles. The area of the large triangle is . What is the area, in square units, of one of the small triangles for the actual bridge if the scale factor is 150?

1. 4
2. 112,500
3. 856
4. 10,000

2. 112,500

Step-by-step explanation:

Large triangle: 20

Small triangle: 20/4 = 5

Ratio of areas = (Ratio of sides)²

= 150²

Area = 5 × 150²

= 112,500

1 1/5

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
