Answer:
Explanation:
Question #1:
Area of a triangle = bh/2
A = (3)(6)/2 = 18/2 = 9 in²
Total A = 10 x area of a triangle
Total A = 10 x 9 = 90 in²
Question #2:
A = bh/2
Top 2 triangles: (20)(10)/2 x 2 = 200
Bottom 2 triangles: (20)(50)/2 x 2 = 1000
Total A = 1,200 in²
Question #3:
Total area = 2 triangles + 1 square
Triangle A: must find base
- a² + b² = c²
- 4² + b² = 6²
- b = √(36 - 16) = √20 = 2√5
Triangle A = bh/2 = (2√5)(4) = 8√5
Square A = bh = (4)(?)
The last one is very hard, can't find the square's base. I hope the rest of my answers help though! Have a nice day!
