The perimeter of a rectangle is 320mm. If its length increases by 10mm and its breadth decreases by 10mm then it its area will b

wariber [46]

Answer:

The length of the original rectangle is 73.4 mm.

The breadth of the original rectangle is 86.6 mm.

Step-by-step explanation:

Given : The perimeter of a rectangle is 320 mm. If its length increases by 10 mm and its breadth decreases by 10 mm then it its area will be 32 less.

To find : Calculate the length and breadth of the original rectangle ?

Solution :

The area of the rectangle is $A=L\times B$

Let the length of the rectangle be 'x'

The breadth of the rectangle be 'y'

The area is $A=xy$

Now, length increases by 10 mm i.e. L=x+10

breadth decreases by 10 mm i.e. B=y-10

The new area is $A_n=(x+10)(y-10)$

According to question,

$A-A_n=32$

$xy-(x+10)(y-10)=32$ ......(1)

The perimeter of a rectangle is 320 mm.

i.e. $P=2(L+B)$

$320=2(x+y)$

$x+y=160$

$x=160-y$ .....(2)

Substitute the value of y from eqn (2) in (1),

$y(160-y)-(160-y+10)(y-10)=32$

$160y-y^2-(170-y)(y-10)=32$

$160y-y^2-(180y-1700-y^2)=32$

$160y-y^2-180y+1700+y^2=32$

$1700-20y=32$

$20y=1732$

$y=\frac{1732}{20}$

$y=86.6$

Substitute in (2),

$x=160-86.6$

$x=73.4$

The length of the original rectangle is 73.4 mm.

The breadth of the original rectangle is 86.6 mm.

Graph y= –3x+4. (I WILL MARK BRAINLIEST)

Ne4ueva [31]

Answer:

See attached

Step-by-step explanation:

<u>Given function:</u>

y= –3x + 4

To graph the line we need two points

One of the easy points is the y-intercept:

(0, 4)

Another point can be taken depending on the slope. With the slope of -3, we select x = 2 and find its y- coordinate:

y = -3(2) + 4 = -6 + 4 = -2

So we have points

(0, 4) and (2, -2)

Plot these points and connect with the line and we are done.
