L=n-2, W=4+L=n+2
A=LW, since L=n-2 and W=n+2 we have:
A=(n-2)(n+2) so it could be this expression or the expansion
A=n^2-4
Answer:
28 cm^2
Step-by-step explanation:
a= ( b1+ b2 / 2 ) h
a= ( 5+9 /2)*4
5+ 9 = 14
14/2=7
7*4 =28
if all the squares are the same size then 10 can be made because squares have 4 sides and 40/4= 10
Answer:
x = 15
Step-by-step explanation:
