Length= 6 Width= 3
the formula to find the perimeter in a rectangle is 2(L+W)=perimeter
they gave us the perimeter so we substitute is into the equation:
2(L+W)=18
substitute the W by 1/2L
u will end up with 2(L+1/2L)=18
distribute the 2 and u will get:
2L+1L=18 which is 3L=18 and L=6
we know that the width is half the length so W=1/2(6) so W=3
Answer:
3 lol
Step-by-step explanation:
Just substitute 3 for x, and it’s 3+1=4. Your answer is 4!
Answer:
Step-by-step explanation:
Add to both sides:
Subtract 2 from both sides:
Divide both side by 2:
Answer:
perimeter of circle=2πr
16=2πr
r=16/2π=8/πcm
now.
area of circle=πr²=π(8/π)²=π×64/π²=64/(22/7)=64×7/22=20.36cm²
