Answer: I don’t know how to solve the area of these shapes. But I know how to find the peeimeter Of this shape.

perimeter=P

finding the P of any shape is like finding the P of a square or rectangle. Is to add up all the sides up like for the 8th one it would be 10+20+20+10 or (10x2)+(20x2)

hope this helps!

Help me plz this is hard

cricket20 [7]

you first use distributive property for the multiplication

[(2*4x)-(2*11)]+9=19

8x-22+9=19

Then, you need to leave the variable alone moving all the other numbers with the opposite operation (addition to substraction, substraction to addition, multiplication to division, division to multiplication)

8x=19+22-9

8x=(19+22)-9

8x=41-9

8x=32

Then as 8 and x are multiplying you pass it dividing

x=32/8

x=4
