Question

The breadth of a rectangle is 3/4 of its length. If the perimeter is 168cm then find the length.​

Answer 1

Answer:

Length of the rectangle is 48 cm.

Step-by-step explanation:

Given:

Perimeter of rectangle =168 cm.

Here it is given that breadth is 3/4 of its length.

So,

Let length (l) of rectangle be X cm.

Then breadth (b) be 3/4 of X

         Breadth = 3X/4

As we know that,

perimeter of rectangle = 2 (l + b)

                                168=2 ( X + 3X/4 )

                                168/2= (4X +3X)/4

                                 84 = 7X /4

                               84 × 4 = 7X

                             336/7 = X

                               48 = X

Length = X 48 cm.
