The length of a rectangle is 5cm more than its breadth . if the perimeter of the rectangle is 40 cm , find the dimensions f the rectangle
2 answers:
Step-by-step explanation:
find
length and the breath
<h2> given</h2>
<h2>solution </h2>
length = x +5
<h2>perimeter 2 L+ B</h2>
<h3>2 x + x = 40</h3>
2 x + 5 = 40 / 2
2x + 5 = 20
2 x = 20 -5
2 x + 15
x = 15 /2

<h3>Answer :- </h3>
<h3>Solution :- </h3>
Let the breadth of the rectangle be x cm
length of the rectangle = ( x + 5 ) cm perimeter of the rectangle= 2( l + b )
2 ( x + x + 5 ) cm 2 ( 2x + 5 ) cm ( 4x + 10 ) cm
<em><u>Transpose </u></em> <em><u>1</u></em> <em><u>0</u></em> <em><u> </u></em> <em><u>to </u></em> <em><u>RHS </u></em>
<em>therefore</em><em> </em><em>,</em><em> </em> 4x +<em> </em>10 = 40 4 x = 40 - 10 x = 30 / 4 = 67.5
Length of the rectangle = x + 5 = 7.5 + 5 = 12.5 Breadth of the rectangle = x = 7.5 cm

The general slope-intercept form equation is:
In this case, m=-2 and with the point (4, 10) we can find the value of b:
We found that b = 18, so:
Answer:
15
Step-by-step explanation:
30% of 50 is 15 beacuase 50 is 1/2 of 100, and of 100 students 30 would have submtted forms. 1/2 of 30 is 15 which s the number of students that turned n forms
