The width of a rectangle is 6 ft. What os the perimeter of the rectangle if its area is 42 square feet? A 26 feet B 36 feet C 42 feet D 48 feet

Area (rectangle) = lenght x width

width = 6 ft

area=42 ft²

1) we have to calculate the length.

42 ft²=lenght x 6 ft

length=42 ft²/6 ft=7 ft

2) Now we have to calculate the perimeter.

Perimeter=2 lenght + 2 width

Perimeter=2 (7 ft) + 2 (6 ft) = 14 ft + 12 ft=26 ft

answer: the perimeter is 26 ft.
