Question

Two sides of a rectangle are both 4 inches. If the

perimeter is 30 inches, write and solve a two-step
equation to find the missing lengths. Help

Answer 1

Answer: 2(4)+2b=30 /missing lenght=11

Step-by-step explanation: We know the equation of a rectangle is 2a+2b=perimeter "a" and "b" both represent a side length

2(4)+2b=30 <--- Plug in the know side lenght

8+2b=30

8(-8)+2b=30(-8) <--- Subtract "8" from both sides to further solve

2b=22

2b/2=22/2 <--- Divide each side by "2"

b=11
