Finding the perimeter or area of a rectangle given one of th

Mathematics
1 answer:
babymother [125]3 years ago

Answer:

<h3>The answer is 70cm</h3>

Step-by-step explanation:

Perimeter of a rectangle = 2l + 2w

Area of a rectangle = l × w

where

l is the length

w is the width

From the question

The length of a rectangle six times its width which is written as

l = 6w

Area = 150cm²

Substitute these values into the formula for finding the area

That's

150 = 6w²

Divide both sides by 6

w² = 25

Find the square root of both sides

width = 5cm

Substitute this value into l = 6w

That's

l = 6(5)

length = 30cm

So the perimeter of the rectangle is

2(30) + 2(5)

= 60 + 10

<h2>= 70cm</h2>

Hope this helps you

I believe the answer is 64
First break it off into 2 rectangles on is 4 width and 10 length other is 8 length and 10 width. Then multiple to find area 10•4=40 8•3=24 then add 40+24= 64

Answer: y=4/5x-2 or y=4/5x+(-2)

Step-by-step explanation:

The formula for slope-intercept form is y=mx+b.

To find the slope, we can use the formula m=\frac{y_{2}-y_{1}  }{x_{2}-x_{1}  } and plugging in the points given.

m=\frac{6-2}{10-5} =\frac{4}{5}

We know our slope is 4/5. We can plug this into our slope-intercept form and then plug in a point to find b, y-intercept.

y=\frac{4}{5} x+b

2=\frac{4}{5}(5)+b

2=4+b

b=-2

We know the y-intercept is -2.

THe final equation is y=4/5x-2 or y=4/5x+(-2).
