Answer:
(1)
Let the breadth be b , then length be 3b ,
Perimeter = 2(l+b)
36 = 2(b+3b)
36 = 8b
b = 36/8 = 4.5cm
l = 4.5 x 3 = 13.5cm
(2)
Let after X weeks they have same money , then
435 + 25X = 875 - 15X
40X = 875-435 = 440
X = 440/40 = 11
So , after 11 weeks , they will have same money

Weight of 50 cans = 312
Weight of a can = 312/50
Weight of 70 cans = 312/50 x 70

Total members = 18
Let she buys P t-shirts , and (18 - P) sweatshirts
According to question ,
9P + 15(18-P) = 180
9P +270 - 15P = 180
15P - 9P = 270 - 180
6P = 90
P = 90/6 = 15
So , number of t-shirts are 15 and number of sweatshirts are 18-15 = 3 .
Hope this helps ,
