Question

the length of a rectangle is 15 more than its breadth if the perimeter of rectangle is 80 m find the dimensions of the rectangle​

Answer 1

Answer:

l= 27.5 m

b= 12.5 m

Step-by-step explanation:

let breadth of the rectangle be (x) m

therefore, the length of the rectangle = (x + 15) m

so, we know that

perimeter of rectangle = 2(l+b)

80 = 2 ( x+x+15)

40 = 2x +15

x = 25/2

= 12.5 m

therefore, the breadth of the rectangle is 12.5 m

whereas the length of the rectangle is 27.5 m.

CHEERS!!

Answer 2

Answer:

12.5

Explanation:- Perimeter = 2× (l+b)

80=2×( [ 15+b ] + b )

80÷2=15 + b + b

40 = 15+ 2b

40 - 15 = 2b

25/2 = b

Therefore, breadth = 12.5

length = 12.5+15 = 27.5
