lenght=15, width= 10
Length of rectangle garden is 5 m greater than the width. the area is 84 m2. find the dimensions of the garden.
Let the length be 2x and the width be x: length*width = area 2x*x = 50 2x2 = 50 x2 = 25 x = 5 feet
Rectangular perimeter = 2(Length + Width) Width = a Length = a+5 Then, 84 = 2(a+a+5) 42 = 2a+5 (42-5)/2 = a = 18.5m = Width Length = a+5 = 23.5m
Surface area = 2*(L*W + W*H + H*L) = 324 m2
