8 < 2b
8/2 < b
4 < b
2b + 15 < 5
2b < 5 - 15
2b < -10
b < -10/2
b < -5
answer is : b > 4 or b < -5
Answer:
<u>Rs. 72</u>
Step-by-step explanation:
We have 2 values here,
- Perimeter of the rectangle = 360 cm
- Breadth of the rectangle (b) = 60 cm.
Firstly, we must find the length of the rectangle (l).
So, according to the formula,
Perimeter = 2 (b + l)
360 = 2 (60 + l)
360 = 120 + 2l
360 - 120 = 2l
240 = 2l
120 cm = l
Now, we need to find the area of the rectangular wall & then convert it from cm² to m² as the cost of painting is given in m².
So,
Area = lb
Area = 120 × 60
Area = 7,200 cm²
Let's convert it to m² now,
7200/1000
= 7.2 m²
Given, cost of painting per m² = Rs. 10
So, the cost of painting the wall is,
10 × 7.2
= <u>Rs. 72</u>

I would probably distribute 15 with the parentheses 15x 9860 which is 147,900 then you would add 6997+147,900
Y= 154187
