You can put this solution on YOUR website! Madhu's flower garden is now a square.
If she enlarges it by increasing the width 1 meter and the length 3 metres, the area will be 19 square metres more than the present area.
What is the length of a side now?
:
Let s original side of the square
then
(s+3) = the new length
and
(s+1) = the new width
:
New area - old area = 19 sq/m
(s+3)(s+1) - s^2 = 19
FOIL
s^2 + 1s + 3s + 3 - s^2 = 19
do the math
4s = 19 - 3
4s = 16
s = 16/4
s = 4 m the original side of the square
:
:
Check this by finding the area
7*5 = 35
4*4 = 16
----------
dif: 19
