Question

ratio of l:b = 3:1. l=? b=?
perimeter =36. rectangle ​

Answer 1

Answer:

we know P=2(3x+x)

              so 36=2*4x

                so x=36/8=9/4

Step-by-step explanation:

Let The breadth,b be x. then length , l = 3x

Answer 2

Question;✧･ﾟ: *✧･ﾟ:*༶•┈♛

ratio of l:b = 3:1. l=? b=?

perimeter =36. rectangle

Given;»»————>

Dimension in the ratio l:b = 3:1

perimeter = 36.

To find;░░

■□■Dimension of rectangle..

Solution;▼△▼△▼△▼△

let the dimension of rectangle be x.

so,▤

l = 3x,

b = x.

then,▥

perimeter = 2(l+b)

36 = 2(3x + x)

36 = 6x+2x

36 = 8x

x = 36/8

x = 4.5

To verify;♤♤

l = 3x = (3×4.5) = 13.5

b = x = 4.5

□□Perimeter = 2(l+b)

36 = 2(13.5+4.5)

36 = 27+9

36 = 36

♡♡ HENCE, PROVED♡♡

✚✚ IT'S CORRECT.. ☑☑☑

Analysis;»»——⍟——««

perimeter of rectangle is 36. and we have to let the ratio be x to find the dimension of the rectangle...

Formula to use;☆♬○♩●♪✧♩　　

perimeter of rectangle= 2(l+b)
