Answer:2.8 feet
Step-by-step explanation:
length(l)=?
breadth(b)= 1.9 feet
perimeter(p)=7.4 feet
we know,
p=2(l+b)
7.4=2(l+1.9)
7.4=2l+3.8
2l=7.4-3.8 (changing side and bringing 3.8 to 7.4 it gets -3.8)
l=3.6/2
l=2.8 feet
Hence,length is 2.8 feet

Answer:
c=4
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2(c+1)=10
(2)(c)+(2)(1)=10(Distribute)
2c+2=10
Step 2: Subtract 2 from both sides.
2c+2−2=10−2
2c=8
Step 3: Divide both sides by 2.
2c
2
=
8
2
c=4
