5^2 is 25 and 25x6 is 150sq ft
Answer:
Kian's method is correct.
Step-by-step explanation:
Javine says, "To multiply by 1000, I just add three zeros." He is incorrect.
Kian says, "I times by 10, then times by 10 and times by 10 again. When he multiply 1 by 10, it becomes 10. Then if he again multiply by 10, it becomes 10×10 = 100. And at last when he multiply again 10, it becomes 100×10 = 1000. It means Kian's methods for multiplying by 1000 is correct.
100 times (6+5)
100 times 11
100 groups of 11=1100
Hope I helped:)
B) 35
the formula is .5(outer angle - inner angle) = .5(100-30)=.5*70=35
