Answer:
perimeter is 12x-6
Step-by-step explanation:
perimeter is the sum of all sides
3(x+2) + 2x+11 + 7x-23
distribute the 3 in the first term, then combine 'like terms'
3x+6 + 2x+11 + 7x-23
3x+2x+7x + 6+11+(-23)
12x-6
Answer:
Option (b) is correct.
Area of rectangle is 36 units
We have,
⇒36=6×6
=2×3×3×2
=4×9
Hence, the sides of a rectangle are 4cm and 9cm
Perimeter =2(l+b)
=2(4+9)
=13×2
=26units
1cm = 2.5 ft
0.5 cm = 1.25 ft
Circumference = πD
Circumference = π(1.25)
Circumference = 3.93 ft
Answer: 3.93 ft
