Question

Hi

Pls help me do the 2nd one.Plss

Answer 1

Hi mate here is the answer:---

Let" l "be length and breadth be" b"

Given:- Perimeter of rectangle = 154 m

Length is two more than twice of breadth,

twice of breadth means 2 b, and 2 more than this means : 2 b + 2

Therefore,

l = (2 b + 2) m

Then, perimeter = 2 (l + b) = 154 m

Putting the value of l in above equation,

2{(2 b + 2) + b} = 154

2{3 b + 2} = 154

6 b + 4 = 154

6 b = 154 - 4

6 b = 150

b= 150/6 = 25

Hence, Breadth of the rectangle = 25 m

So, length of the rectangle = 2 b + 2 = 2 (25) + 2 = 52 m

Hope it helps you ❣️❣️

Answer 2

Solution-

Let the breadth be x.

So,the length=2+2x

Perimeter=154m

2(l+b)=154

2(2+2x+x)=154

2*(2+3x)=154

2+3x=77

3x=75

x=25

Length=52m

Breadth=25m.

Hope it helps you
