Answer:
Confidence limit = [52.8%, 75.2%]
Step-by-step explanation:
±
where the value will be taken from the z-table for 95% confidence interval
1-0.95= 0.05/2= 0.025
0.95+0.025= 0.0975
From the z-table the value of corresponding to 0.0975 is 1.96
±

Area and perimeter of figure be: 562.08 m² and 123.68 m
<h3>What is Area and perimeter?</h3>
Perimeter is the distance around the outside of a shape. Area measures the space inside a shape.
The figure comprises of a parallelogram and semicircle.
1. For Area
Area of parallelogram = base x height
= 24 x 14
= 336 m²
Area of semicircle = (π x r²)/2
= (3.14 * 12 * 12)/2
= 226.08 m²
Total Area of the figure = 336+ 226.08 =562.08 m²
2. Perimeter
Perimeter of parallelogram= 2 (a+b)
= 2 (19 +24)
= 86 m
Perimeter of semicircle= π * r
= 3.14 * 12
= 37.68 m
Total Perimeter of the figure= 86 + 37.68 = 123.68 m

Answer:
3 StartRoot 2 EndRoot + 2 StartRoot 5 EndRoot units
Step-by-step explanation:
we know that
The isosceles trapezoid has
:
Two parallel sides not equal in length called its bases (KL and NM)
Two non-parallel sides equal in length (LM and NK)
so
The perimeter is equal to
substitute the values
3 StartRoot 2 EndRoot + 2 StartRoot 5 EndRoot units
