Question

what will be the lenght of the rectangle if breadth and perimeter is given

Answer 1

HEY MATE,_________________↓↓↓

SUPPOSE, THE PERIMETER IS 10CM

AND, THE BREADTH IS 2CM.

LET, THE LENGTH BE X CM.

WE KNOW THAT,

PERIMETER = 2(LENGTH + BREADTH)

⇒ 10. = 2(X + 2)

⇒ 10/2 = X + 2

⇒ 5. - 2 = X

⇒ 3. = X

∴ LENGTH = 3CM.
