Question

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

Answer 1

Answer:

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
