252mmSquared
Step-by-step explanation:
28+28=56
74-56=18
18÷2=9
9×28=252
Answer:
A=252
B=28mm
P=74mm
we know the two sides of B= 28
28+28= 56
the perimeter is every added up P= 74
so we must minus 56-74 = 18
meaning side A= 18 then we divide it by 2 which is 9
to check... 9+ 28+9+28 = 74 same answer if 18+56= 74
Formula for Area = Lxw meaning 9x28
9x28 = 252
C. Both can be used to withdraw money from ATMs.
The answer is 1,000
25
Note x^2y + xy^2 = xy(x+y)
We know xy = 5 and x+y = 5, so
5*5=25
