Question

the length of rectangle is 16 m less than 2 times its breadth if the perimeter of the rectangle is 122 find the length and breadth​

Answer 1

Answer:

Answer

Let l be the length of rectangle

and b be the breath of rectangle

A/Q,

l=2b−16⟶(1)

also,perimeter=112m

⇒2(l+b)=112

⇒2(2b−16+b)=112(from(1))

⇒b=24m

and,

l=2.24−16

⇒l=32m

Step-by-step explanation:

here is your answer

Answer 2

$\bold\blue{Answer:-}$

Let the length& breadth of the Rectangle be 'l' &,'b' respectively.

As per the Question,

l = 2b - 16 ---(1)

Perimeter = 122m

$\implies$ 2(l+b) = 122

$\implies$ 2(2b-16+b) = 122 ---[from (1)]

$\implies$ 2(3b-16)=122

$\implies$ 6b = 122+16=138

$\implies \:b\: = \dfrac{138}{6} = 23$

Breadth = 23m

$\:$

Length = 2 × 23 - 16 = 30

$\implies$ l = 30 m
