Question

the length of a rectangle is 7 M more than its breadth if its perimeter is 50 metre find the length and breadth of the rectangle

Answer 1

Hey,

Let the breadth of the rectangle be X m,

Length = (7+x) m

Perimeter = 50 m

50 = 2(x+7+x)

25 = 7+2x

18 = 2x

X = 9 m.

Therefore, Length = (9+7)m = 16 m and Breadth = 9 m.

Hope this helps you buddy!!
Take care always ##

Answer 2

let x be the breadth 
length = x+7
now perimetre = 50m
2(x+x+7) =50
2x+7 = 50/2
2x = 25-7
x = 18/2
x = 9 m
and length =  9+7 = 15




mark me as a brainlist if the answer is satisfactory and make u understand.
please if answer is satisfied then dont foget to thanks also....................
