The length of a rectangle is 3 more than twice its width. the perimeter is 48 feet. what is the length and width of this rectangle?

The rectangle equals 48 ft. the width can be called x and the length is 3x.
2(x+3x)=48
2x+6x=48
8x=48
x=6
Width         Length
x=6             3x=18

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
