Question

4. The length and breadth of a rectangle are in a 15:11 ratio. If the length is 56 cm more than the breadth, find the perimeter of the rectangle.​

Answer 1

Answer:

Answer Is -728

Step-by-step explanation:

We know that the Length of the rectangle is 15/11ths of the Breadth:

1) L = 15/11 * B

We know that the difference between Length and Breadth is 56:

2) L - B = 56

Substituting the second equation into the first:

15/11 * B - B = 56

15/11 * B - 11/11 * B = 56

4/11 * B = 56

B = 56 * 11/4 = 154

We can test our calculation of B by calculating L and checking the difference:

L = 15/11 * B = 15/11 * 154 = 210, and the difference is

L - B = 210 - 154 = 56

Knowing the Length and Breadth, we can calculate the perimeter as 2*B + 2*L:

Perimeter = 2 * 154 + 2 * 210 = 728
