The perimeter of Peter's rectangular garden is 98 meters. The width of the garden is 60% shorter than its length.
Find the dimensions of the rectangular garden in meters.
Find the garden area in square meters.

Correct answer:

a =  35 m
b =  14 m
S =  490 m2

Step-by-step explanation:

o=98 m b = a  0.60a  o = 2(a+b)  o=2 (a+(a0.60 a)) 98=2 (a+(a0.60 a))  2.8a=98  a=2.898=35  a=35=35 m
b=a0.60a=350.60 35=14 m
S=a b=35 14=490 m2
