If the width and length of a rectangle are both increased by 10%, by what percent does the area of the rectangle increase?
S_A_V [24]

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%

I hope this helped and if it did, please mark as Brainliest.

On a number line, suppose point E has a coordinate of 4, and EG = 11. What are the possible coordinates of point G?
navik [9.2K]

Answer:

  -7, 15

Step-by-step explanation:

The positive difference between E and G is 11.

<h3>Solution</h3>

  G - E = 11

  G = 11 + E = 11 + 4

  G = 15 . . . . . . . . . . . . . when G is right of E

__

  E - G = 11

  E - 11 = G = 4 - 11

  G = -7 . . . . . . . . . . . . when G is left of E

Possible coordinates for G are -7 and 15.
