Question

The length of the rectangle is double of its breadth. If the perimeter is 78, find it's length and breadth.​

Answer 1

Interstate disparities in layman's terms are the proportion of poor people of one particular geographical boundary or State is not the same in other States as well. ... In India, it is recorded that Orissa and Bihar are the two states which are the poorest with poverty ratio of 47 and 43%.

Answer 2

________________________________

✧ Solution ↓

________________________________

➠ Let the breadth be x, then length will be 2x.

________________________________

➠ We know that :-

➠ Perimeter = 2(Length + Breadth)

________________________________

➠ According to question :-

➠ Perimeter = 2(2x+ x)

➠ 78 = 2(3x)

➠ 78 = 6x

➠ $\dfrac{78}{6}$ = x

➠ 13 = x

➠ Value of x = 13

________________________________

Therefore,

⇒ Length = 2x = 2(13) = 26

⇒ Breadth = x = 13

✧ Verification ↓

________________________________

➠ 78 = 2(2x + x)

➠ 78 = 2(3x)

➠ 78 = 6x

➠ 78 = 6(13)

➠ 78 = 78

➠ LHS = RHS

Hence, verified.
