Question

The length of a rectangle is 1/3 of its breadth . if the perimeter is 64m, then find the length and breadth of the rectangle ​

Answer 1

Answer:

let, breadth = 3x

then, length = x

perimeter of rectangle 2(l+b)

=2(3x+x) = 64

= 8x = 64

=x =64/8 = 8m.

length = 8m.

breadth = 8×3 =24m.

Answer 2

Answer:

Length = 8 metre and Breadth = 24 metre

Step-by-step explanation:

Length = 1/3×Breadth

L = 1/3×B

Perimeter= 2(L+B)

64 = 2(1/3×B+B)

32 = 4/3×B

B = 32×3/4

B = 8×3

B = 24

L = 1/3×B

L = 1/3×24

L = 8
