Question

Breadth and length of rectangle is in the ratio 7:11. Length is 20 cm and more than the breadth and length

Answer 1

Breadth = 35 cm

Length = 55 cm

Step-by-step explanation:

Breadth : length = 7 : 11

Breadth = 7x

Length = 11x

Length is 20 cm more than breadth.

Length = breadth + 20

11x = 7x + 20

11x - 7x = 20

4x = 20

x = 20/4

x = 5

Breadth = 7x = 7*5 = 35 cm

Length = 11x = 11 * 5 = 55 cm

Answer 2

breadth = 7x

length = 11x

length is 20 cm more than the breadth

7x+20 = 11x

20 = 11x-7x

20 = 4x

X = 20/4

X = 5

braedth = 7×5 = 35 + 20 = 55

length = 11×5 =55
