Adiana has a rectangular garden that measures 9 m wide and 13 m long. She wants to increase the area to 192 m^2 by increasing the width and the height by the same length. What will be the new length of the garden? A. 16 m B. 15 m C. 14 m D. 13 m
length of first rectangle = 13m , width = 9m area = 13 *9 =117 m^2-----(1) increase in area = 192m^2----(2) area of the new rectangle = 117 + 192 = 364 m^2----(3) i l = 13 , width = w area = 364 m^2 l*w =364 13 * w= 364 find the width ? and find the difference between first width and second width
do u understand !
I think so, so are you saying the answer is 13 m?
yea its 13
Thanks
np
It was 16
w = 364/13 new width = 28 length is 13 , it is same according to the problem
You misread the question. The NEW area was 192, so X the increase in both length and width is 3. Solving for the root that makes sense. The new length is 13 + 3 = 16 |dw:1458226174682:dw|
