Question

The length of rectangle is 3cm less than twice its breadth perimeter is 48cm.find the length and breadth

Answer 1

Answer:

breadth = 7

length = 11

Step-by-step explanation:

let breadth be x

its given that length is 3cm less than twice its breadth which mathematically means

2x -- 3 = length

x = breadth

as we know

perimeter of rectangle is equal to 2(l+b)

substituting values we get 2(2x--3 + x) = 48

on solving we get

➡️3x -- 3 = 24

➡️3x = 21

➡️x = 7

therefore breadth is equal to 7

now put the value in length equation.

therefore length is

2×7 -- 3

which is equal to 11

hope this helps u....

Answer 2

Answer:

length=17, breadth =7

Let length=l, breadth =b

Given

l =2b-3

perimeter =2(l-b)=24

on evaluating eqn we get l=17 and b=7
