Question

Ratio of breadth and length of a rectangle is 8:5 if breadth is 60 meter less than length then find the perimeter

Answer 1

Length:Breadth = 8:5 [i hope either the ratio given is L:B or it should be 'length is 60 m less than breadth']
L:B = 8:5
Length = 60+Breadth
Length - Breadth = 60
8:5----8x:5x
8x-5x = 60
3x = 60
x = 20
L=8x = 160
B= 5x = 100
Perimeter= 2[L+B] = 2[160+100] = 2*260 = 520 m
