Question 117
The length of a floor is 125% of its breadth. If the area of floor is $$320m^2$$, what is the sum of the length and the breadth of the floor? (in m)
Solution
LET THE LENGTH BE L AND BREADTH BE B OF THE FLOOR.
L = 1.25 B (GIVEN)
L*B = 320
SOLVING, BOTH THE EQUATIONS, WE GET
B = 16 AND L = 20
L + B = 36 M
