Answer:
11. 1520 mm.
12. 24 meters.
Explanation:
11. To find the width of the rectangle, we can use the formula for the area of a rectangle:
Area = length x width
Substituting the given values, we get:
657,504 = 432 x width
Solving for width, we get:
width = 657,504 / 432
width ≈ 1520 mm
Therefore, the width of the rectangle is approximately 1520 mm.
12. To find the length of the base of the trapezoid, we can use the formula for the area of a trapezoid:
Area = (1/2) x (top + bottom) x height
Substituting the given values, we get:
150 = (1/2) x (6 + bottom) x 10
Simplifying, we get:
150 = 5(6 + bottom)
Dividing both sides by 5, we get:
30 = 6 + bottom
Subtracting 6 from both sides, we get:
bottom = 24
Therefore, the length of the base (bottom line) of the trapezoid is 24 meters.
