the ratio between length and breadth is
7:3. Find the area of the rectangle.​

Answer 1

Answer:

the answer of this question is

Answer 2

Answer:

let the ratio be x so

length is 7x and breadth 3x

perimeter is 2(L+B) = 30

L+B = 15

7x +3x = 15

10x = 15

x = 1.5

so

length is 1.5 × 7 = 10.5

breadth is 1.5 × 3 = 4.5
