Question

a rectangle has an area of 228 ft squared and a lengthy that measures 12 ft find the perimeter of the rectangle

Answer 1

Since you have 2/3 values given, you can solve this.
The equation for area in a rectangle is
L*W=A.
Replace the variables
12*W=228.
Now divide by twelve on both sides.
W=19
Now that you have found width, find perimeter.
2L+2W=P
2*12+2*19=P
24+38=62.
