twice its breadth. What are the length and the breadth of the pool?
7 cm and BD = 5 cm.
A​

Answer 1

Step-by-step explanation:

perimeter of rectangle=l×b

Answer 2

Answer:

let the breath of the pool be x metre

then,

the length of the pool = (2x + 2) m

perimeter = 2(l+b)

154 = 2 (2 x+2+x)

154/2 = 2x+2+ x

77 = 3x + 2

77-2 = 3x

75 = 3x

x = 75/3

x = 25 m

length of the pool = 2x + 2

= 2×25+2

= 52 m

breadth of the pool = 25 m
