A rectangle sticker had a perimeter of 32 centimeters and a area of 48 square centimeters. what are the dimensions of the sticke

vovangra [49]

Answer:

4 cm ×12 cm

Step-by-step explanation:

To find the dimensions of the sticker, start by forming 2 equations for its area and perimeter.

Perimeter of rectangle= 2(length +breadth)

Let the length and breadth of the rectangle be L and B cm respectively.

2(L +B)= 32

Divide both sides by 2:

L +B= 16 -----(1)

Area of rectangle= length ×breadth

LB= 48 -----(2)

From (1): L= 16 -B -----(3)

Substitute (3) into (2):

(16 -B)(B)= 48

Expand:

16B -B²= 48

B² -16B +48= 0

(B -4)(B -12)= 0

B -4= 0 or B -12= 0

B= 4 or B= 12

Substitute into (3):

L= 16 -4 or L= 16 -12

L= 12 or L= 4

Thus, the dimensions of the sticker is 4 cm ×12 cm.

Solve these plz and give a explanation <br>

Answer:

$\large{ \tt{☄ \: EXPLANATION}} :$

✎ Firstly , Remember these things :

To convert the percentage into a decimal fraction, remove the % symbol and divide it by 100 as in the case of conversion of percentage into fraction. We know that , divide by 100 means shifting to the left ; so to convert a percentage into decimal fraction, remove the % symbol and shift the decimal point two places to the left. For example : $12\% = \frac{12}{100} = \boxed{ 0.12}$

$\large{ \tt{☥ \: LET'S \: SOLVE}} :$

$\large{1. \: \: 52\% \: \text{of} \: 210 = \frac{52}{100} \times 210 = 0.52 \times 210 = \boxed{109.2} }$

$\large{ 2. \: \: 35\% \: \text{of} \: 500 = \frac{35}{100} \times 500 = 0.35 \times 500 = \boxed{175} }$

$\large{3. \: 28\% \: \text{of} \: 866 = \frac{28}{100} \times 866 = 0.28 \times 366 = \boxed{102.48} }$

$\large{ \tt{✺ \: REPEAT \: DAILY} }:$

I will remain focused on my goals. Even if I have a moment of difficulty , I will not give up. I know Success comes with consistency. I know that I will make it. Things will get better. No problem or challenge will stop me. Everything I deserve is coming my way.

ツ Hope I helped! ۵

the length of a rectangle is five feet less than its width. If the area of the rectangle is 84 square feet, find its dimensions

KIM [24]

Let
x---------> the length of the rectangle
y--------> the width of the rectangle

we know that
A=84 ft²
[area of rectangle]=x*y-----> 84=x*y-----> equation 1
x=y-5------> equation 2
substitute 2 in 1
84=[y-5]*y-----> 84=y²-5y---------> y²-5y-84=0

using a graph tool-----> to resolve the second order equation
see the attached figure

the solution is
y=12
x=y-5-----> x=12-5-----> x=7

the answer is
the length of the rectangle is 7 ft
the width of the rectangle is 12 ft
