Question

The ratio of the length and breadth of a rectangular field is 4: 3. If the perimeter of the rectangular field is 70 meters, what will be its breadth (in meters)? (A) 15 (B) 24 (C) 18 (D) 12​

Answer 1

Answer:

The ratio of the length and breadth of a rectangular field is 4: 3. If the perimeter of the rectangular field is 70 meters, its breadth (in meters) is 20 cm.

Step-by-step explanation:

If the ratio of the length and breadth of a rectangular field is 4: 3.

If the common multiple is x

length of rectangle = 4x

breadth of rectangle = 3x

If the perimeter of the rectangular field is 70 meters

The perimeter of the rectangle = 2 (Length + breadth)

2(4x + 3x) = 70

2(7x)= 70

14 x= 70

x = 70/14

x = 5

So, length of rectangular field = 4x = 4 (5) = 20 m.
