Answer:
Step-by-step explanation:
Lila and Wassim shared a tent rectangular tent beetween them
the area of the base is :
A= 2.3*4.2 = 9.66 m² < 10m²
so they will pay 15 pound per night
they stayed 10 nights
for 5 nights one is free so for 10 nights 2 are free
then : they will only pay 8 nights
so 8*15= 120£
They saved 13 pounds for 9 weeks
so they have 117 pounds
so they didn't save enough money
