Question

Find the length and breadth of the rectangle given below if its perimeter is 72 m​

Answer 1

perimeter = 2(L+B) = 72

L+ B = 36

we can find the sum of length and breadth but we can not tell them individually because there is no another link is given ( i.e their ratio or one of them)

Answer 2

Step-by-step explanation:

Given sp=220 and loss=12%

so, the CP = (220*100)/88 =250 Rs

now the new profit is 10% and cp is 250 Rs

and we have to find by how much amount as compared to earlier the SP will be more so as to gain profit of 10%.

so SP= (250*110)/100 =275 Rs

now increase in amount= 275–220 = 55 Rs
