Answer 1

Answer:

Step-by-step explanation:

Hey mate here is your answer:

_____________________________________

Given:

→Length of rectangle is thrice of its breadth.

→Perimeter : 24 cm.

__________________________________

To find:

→Dimensions(Length and breadth).

___________________________________

Solution:

→Let length be 3x and breadth be x.

→As you know perimeter of the rectangle

= 2(length + breadth),

→Substitute the values given,

→$2(3x+x)=24,$

→$2(4x)=24,$

→$8x=24(I)\:\:or\:\: 4x=\frac{24}{2}(II)$,

→$x=\frac{24}{8}$ $or\:\:4x=12$,

→$x=3(I)$.

→$x=\frac{12}{4} (II),$

→$x=3(II)$.

So:

Length = 3(x) = 3(3) = 9 cm.

Breadth = x = 3 cm.
