Since the length of this rectangle is twice its breadth, the length is equal to 40 cm.
<h3>How to calculate the area of a rectangle?</h3>
Mathematically, the area of a rectangle can be calculated by using this formula:
Area = Length × Width
Based on the information provided, we have:
- Its length is decreased half of the 10 cm ⇒ (length - 5)
- Its breadth is increased by half of the 10 cm ⇒ (breadth + 5)
- Its area is increased by 75 cm ⇒ (area + 5)
Substituting the parameters into the formula, we have:
LB + 75 = (L - 5)(B + 5)
2B² + 75 = (2B - 5)(2B + 5)
2B² + 75 = 2B(B + 5) - 5(B + 5)
2B² + 75 = 2B² + 10B - 5B - 25
5B = 75 + 25
5B = 100
B = 100/20
B = 20 cm.
For the length, we have:
L = 2B
L = 2 × 20
L = 40 cm.

If 80% of 90 were temerary, 75 would be the answer
To find the domain, you first need to find what x values will result in an imaginary number. To find this, solve the inequality -13-x >(or equal to)0. This comes out to x<(or equal to) -13. This means that’s the domain is [-13, negative infinity).
Answer:
angle A is 94
angle B is 86
Step-by-step explanation:
supplementary angles add up to 180°
(6x + 10) + (4x + 30) = 180
10x + 40 = 180
10x = 140
x = 14
A is 94
B is 86
