Question

The length and breadth of a rectangle are in the ratio 4 : 3. If the breadth is 21 cm, find the length.

Answer 1

Answer:

28

Step-by-step explanation:

Answer 2

The length of the given rectangle is 28 cm.

Given:

the ratio of the length and breadth of a rectangle = 4:3

the breadth of the rectangle = 21 cm

To Find:

we need to find the length of the given rectangle

Solution:

let the breadth of the rectangle be 3x cm

then, the length of the rectangle will be 4x cm

as we know that the breadth is 21 cm,

3x = 21

x = 21/3

x = 7 cm

now, we can calculate the length as-

4x = 4 × 7 = 28

Thus, the length of the given rectangle comes out to be 28 cm.
