+273 The length of a rectangle is 3x+10 feet and its width is x+12 feet. If the perimeter of the rectangle is 76 feet, how many square feet are in the area of the rectangle?
+934 Last question of the day for me, the perimeter of the rectangle is 8x+44 which equals 76, that makes x= 4 feet. The length equals 3*4+10= 22 and the width equals 4+12= 16. The area is 16*22= 352.
Hope it helps!
