Answer: you would tend to take the main dimensions of the shape like height times width and add what you need for the shape that you are finding the area for ; circles= pie2r trinagle=h*w/2 squre=s2 rectangle w*h
Step-by-step explanation:
L=3w-4
Perimeter = 64
64=2L+2w
Plug in L that we solved above into this equation:
64=2(3w-4)+2w
64=6w-8+2w
64=8w-8
72=8w
w=9
Plug W back into the equation above to solve for L
L=3w-4
L=(3)(9)-4
L=23
Check the answer with the perimeter formula:
P=2L+2w
P=2(23)+2(9)
P=46+18
P=64
Factors are what is being multiplied or divided. In this problem, you have 6 times X times Y. So, you have 3 factors.
First plug in the numbers: 3x6+4x12/2. then do the Pemdas, so multiplication first: 18+42/2. then since the division is like a fraction bar, it means to divide but first simplify the 18+42: 60/2. Your answer is 30.
