 Question 293101: I have to create and solve an equation to answer this question. The perimeter of a rectangle is 210m. The length is 7m longer than the width. Determine the dimensions of the rectangle.Answer by checkley77(12569)   (Show Source): You can put this solution on YOUR website!L=W+7 P=2L+2W 210=2(W+7)+2W 210=2W+14+2W 210=4W+14 4W=210-14 4W=196 W=196/4 W=49 ANS. FOR THE WIDTH. L=49+7=56 ANS. FOR THE LENGTH. PROOF: 210=2*56+2*49 210=112+98 210=210
