Answer:
136 m²: 188 m²
Step-by-step explanation:
I think your question missed key information, allow me to add in and hope it will fit the orginal one. Please have a look at the attached photo
My answer:
Given the information:
- The height: 4m
- The lenght: 13m
- The width 4m
The lateral area:
As we know, the lateral area can be calculated by the following formula:
= the perimeter of the base* the height
= (13 + 4 + 13 + 4)*4
= 136 m²
The surface area:
As we know, the lateral area can be calculated by the following formula:
= The lateral area + thhe base area + the top area
= 136 + 13*4 + 13*4
= 136 + 52 + 52
= 240 m2

Answer:
factors are basically numbers that can multiply by another number to get a certain number
Step-by-step explanation:
for example, the factors of 12: 1,2,3,4,6,12
you should count from the lowest to highest number to make it easier for u.
look at 1 and 12 in the sequence. 1 x 12 = 12
now look at 2 and 6. 2 x 6 = 12
now look at 3 and 4. 3 x 4 = 12
see what i mean?
an example of a non-factor would be 5. 5 can't multiply by anything to get 12. You need to find numbers between 1 and the certain number (12 in this example) and you need to find numbers that can multiply by another number to get that certain number but u can't go beyond the certain number. 7 can't multiply by anything to get 12. if u still don't understand, here is an easier way to help u.
the best thing to do is write the numbers from 1 - 12. 1 2 3 4 5 6 7 8 9 10 11 12
once u do that, you need to ask yourself: which numbers can multiply to get 12? 1 can multiply by a number to get 12. 2 can. 3 can. 4 can. <em>5 can't. </em>once you find a number that you can't multiply by, that is <em>not </em>a factor of the certain number you're looking for.
Hope this helps you :D
Answer:
5/7
Step-by-step explanation
When dividing a fraction by a fraction it is the same as multiply the inverse of the bottom fraction, so 5/9 times 9/7 so the 9's cancel and your left with 5/7
Answer:
rs. 52
Step-by-step explanation:
40(70) + 60(80) + 20x = 7200(1.2)
2800 + 4800 + 20x = 8640
7600 + 20x = 8640
20x = 1040
x = 52
