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%

If you have 2 shirts 2 jackets and 2 skirts how many outfits can you make

zvonat [6]

Hello!

If you assume that with each outfit you must use at least one of each shirt, jacket, and skirt, you have a 1/2 chance of selecting one of each. Since it is a compound event (an outfit), you will multiply each singular probability (shirt, jacket, skirt) together.

$\frac{1}{2}$ · $\frac{1}{2}$ · $\frac{1}{2}$ = $\frac{1}{8}$

You can make eight different outfits.

I hope this helps!
