Answer: 832 cm².
Step-by-step explanation:
1. To calculate the lateral area of the prism by using the net you must:
- Calculate the perimeter of the base:
Where l is the lenght and w is the width:
Then:
- Now you must multiply the perimeter by the height. The height is 13 cm.
Then, the lateral surface area is:
Any number that can be evenly divided by 24 without leaving a remainder is a multiple of 24.
We have,
Numbers that have 24 as a multiple includes:
24 (24 x 1)
48 (24 x 2)
72 (24 x 3)
96 (24 x 4)
120 (24 x 5)
144 (24 x 6)
168 (24 x 7)
192 (24 x 8)
216 (24 x 9)
240 (24 x 10)
and so on.
Thus,
Any number that can be evenly divided by 24 without leaving a remainder is a multiple of 24.

and the length is
Answer:
width=6cm, lenth is 7cm
Step-by-step explanation:
Let width of rectangle be x cm
Twice width=2x cm
length=2x-5 cm
Area of the rectangle= L× W =42cm²
(2x-5) × x =42
x(2x-5)=42
2x²-5x-42=0
solving the quadratic equation
x=6cm
width=6cm
length= (2×6)- 5 =7cm
