Question

the length of a rectangle is three times its width it the perimeter of the rectangle is 96 find the length and breadth of the rectangle​

Answer 1

Answer:

Imagine that the breadth of a rectangle is x.

Length = 3 times x = 3x

Perimeter of rectangle = 2(L+B)= 96

= 2(x+3x)= 96

= 2 × 4x = 96

= 8x = 96

= x = 96

8

= x = 12

SO, LENGTH IS 3x = 3×12

BREATH IS x = 12

Answer 2

Answer:

let b = x

and l = 3x

p=2(l+b)

96=2×3x×x

96=6x square

96÷6=x square

16 =x square

16 under root= x

4=x

b=x= 4

l=3x=3×4=12

b=4

l=12

hope this will work plz mark it brillient

thankxxx
