Answer:
10%
Step-by-step explanation:
We know Perimeter of rectangle
= 2 (Length + Width)
If width and length are increased by 10%
New length= L + 10/100L = (1.1) L
New width = W + 10/100W = (1.1) W
Perimeter = 2 [(1.1) L + (1.1) W]
Perimeter = 2 (1.1) (L + W)
Perimeter = (2.2) (L + W)
Increase in perimeter = 2.2 (L + W) - 2 (L + W)
The increase in Perimeter = 0.2 (L + W)
Percent increase
= 0.2 (L + W)/2 (L + W) × 100
= 0.2/2 × 100
= 0.1 × 100
= 10%

Final answer:
When the length and width of a rectangle are increased by 10%, the area increases by 21% and the perimeter increases by 10%.
Explanation:
The area of a rectangle is calculated by the formula Length × Width. If both the length and width are increased by 10%, the new area would be 1.1(length) × 1.1(width), which is 1.21(length × width) or 121% of the original area. So the area increases by 21%. The perimeter of a rectangle is calculated by the formula 2(Length + Width). If both the length and width increase by 10%, the new perimeter would be 2(1.1 Length + 1.1 Width) = 2.2 Length + 2.2 Width, which is 110% or 1.1 times the original perimeter. So the perimeter increases by 10% when you increase the length and width by 10%.

Answer:
39°
Step-by-step explanation:
Internal angles of the triangle are:
- x, 60° and (180° -99°)
Angle x is:
- x = 180° - (60° + 81°)
- x = 180° - 141°
- x = 39°

Answer:
<2, <5, and <7.
Step-by-step explanation:
<2 and 72°, are vertical angles. Vertical angles are congruent. Therefore, <2 ≅ 72°.
<7 and 72° are corresponding angles. Corresponding angles are congruent, therefore, <7 ≅ 72°.
<5 and 72° are alternate interior angles. Alternate interior angles are congruent, therefore, <5 ≅ 72°.
Angles that are congruent to 72° are <2, <5, and <7.
