I need help with this question

Answer 1

we have the equation

`L=x+y+(1)/(2)T`

we have

x=5 1/4 in=5+1/4=21/4 in

y=13 7/8 in=13+7/8=111/8 in

T=1/4 in

substitute the given values in the expression above

`L=(21)/(4)+(111)/(8)+(1)/(2)((1)/(4))`
`L=(21)/(4)+(111)/(8)+(1)/(8)`

Remember that

21/4 is equivalent to 42/8

substitute

`L=(42)/(8)+(111)/(8)+(1)/(8)=(42+111+1)/(8)=(154)/(8)=19.25=19(1)/(4)in`

the answer is

L=19.25 in
