The length of a rectangle is one less than 50% of the width if the perimeter is 31 inches what is the area of the rectangle in feet

Area is 0.34 ft²

Step-by-step explanation:

A=L•w

P=2L+2w

L=w/2-1

31=2(w/2-1)+2w

31=w-2+2w

33=3w

11=w

L=w/2-1

=11/2-2/2

L=9/2

Aft=L/12•w/12

=(9/2)/12•11/12

Aft=0.34

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

step-by-step explanation:

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6
