a garden is in the shape of a rectangle and has a perimeter of 70 yards. the length of the garden is 5 more than twice the width. find the dimensions of the garden.
If the length of the garden is 5 more than twice the width, then length = 2 X width + 5. P = 70 L= 2W + 5 P = 2 X (L + W) 70 = 2 X ((2W+5) + W)) You can take the + 5 out at this point by multiplying it by the 2 outside the brackets (5 for each length) 70 - (2X5) = 2X ((2W) + W) 70 - 10 = 2 X (2W + W) 60 = 2 (3W) 60 = 2*3W 60 = 6W 10 = W The width is 10. So what's the length? 2W + 5 Length = 2 * 10 + 5 Length = 25.
