Question

Find out the length of a rectangle whose perimeter is 390m and breadth is 75m

Answer 1

Hey!

Let the length of the rectangle be x m

Perimeter of a rectangle =2( length+breadth)

Btp,

2(x+75)=390

=> 2x+150=390

=> 2x=390-150

=> 2x=240

=> x=120

Therefore length is 120m

Answer 2

heya
here is your answer

let length of the rectangle = L
breadth of the rectangle = B = 75m
perimeter of rectangle = 390m
2(L+B) = 390
=>2(L+75)= 390
=> L+75 = 390/2 = 195
=> L = 195-75
=> L = 120m

hence the length of the rectangle is 120m.
