Question

THE PERIMETER OF A RECTANGLE IS 52 CM,AND ITS BREATH IS 8CM.FIND ITS LENGTH.

Answer 1

$\huge\text{\underline{\underline{Answer:-}}}$

The perimeter of Rectangle=2(L+B)

Given:-

Perimeter=52cm

Breadth=8cm

Perimeter=2(l+b)

52=2(l+8)

52=2L+16

52-16=2L

36=2L

36÷2=L

18=L

or length=18cm

$\huge\text{\underline{Prove:-}}$

Given:-

Length=18cm

Breadth=8cm

Perimeter:-

2(18+8)

2×26

=52cm

$\huge\boxed{Length\:=18cm}$

Hope it's help uh

Answer 2

Perimeter of a rectangle is $2(l+b)$

Given, perimeter is 52cm and breadth is 8cm.

$2(l + 8) = 52cm$

$l + 8 = \frac{52}{2}$

$l + 8 = 26$

$l = 26 - 8$

$l = 18$

Therefore, the length of the rectangle is 18cm.
