Question

Find the price of 3 door . If the ratio of length and width of 5:3 and Perimeter of door is 48 meter. And price of door is Rs 30 per Sq. Meter.​

Answer 1

LENGTH:BREADTH=5:3

PERIMETER OF THE DOOR =48

LET THE SIDES OF THE DOOR BE 5X AND 3X

ATQ

2(5X+3X)=48

16X=48

X=3

THEN THE LENGTH IS 3*5=15M

AND WIDTH =3*3=9M

AREA OF EACH SQ METRE=Rs 30

THEN TOTAL COST OF THREE DOORS =3(TOTAL PRICE FOR 1 DOOR)

=3(AREA OF EACH DOOR*30)

=3(15*9*30)

=3(4050)

=Rs 12150
