the area of a reactangle mirror is 11 11/16 square feet the width of the mirror is 2 2/4 feet. if there is a 5 foot tall space o
n the wall to hang the mirror will it fit
1 answer:
So square feet is area which is legnth times width or area=lw or a=lw
width=w=2 2/4
2/4=1/2
w=2 1/2=5/2
a=lw
11 11/16=187/16
187/16=l(5/2)
multiply both sides by 2/5 to clear the fraction (1/2 times 2/1=2/2=1)
374/80=legnth
simplify
374/80=187/40=4 27/40=legnth
legnh must be less than 5 and 4 and 27/40 is less than 5 so it will fit
