Presuming the rug covers the patio this is solved using simultaneous equations, with the two variables being the Length (L) and the Width (W)
The first equation is the area: L x W = 36
The second is the relationship between the area and the length: W = L + 5
Thus solving these gives W = 4 feet & L = 9 feet
area = length x width area = 90 feet 10 feet x 9 feet = 90 square feet.
length x width
AREA = LENGTH x WIDTH LENGTH = 2 X WIDTH AREA = 2 x WIDTH X WIDTH = 900 900/2 = WIDTH X WIDTH 450 = WIDTH X WIDTH = WIDTH SQUARED WIDTH = SQUARE ROOT (450) = 21.21 FEET LENGTH = 42.42 FEET

Measure the length and width of the patio area in metres. Times the length by the width to find the square area in metres. For instance: a patio measuring 10 metres by 8 metres: 10 x 8 = 80 square metres.
A cubic yard of gravel will cover 81 square feet at 4" of thickness. Multiply the width of the patio by the length of the patio to get your square footage. Gravel is usually sold by the cubic yard.
Area of a rectangle is length times width, therefore if the length is two feet longer than the width then the length is 9 and the width is 7, when they are multiplied you get 63
200 square feet. To calculate square feet simply multiply length by width - the result is the area in square feet.
The length is 7 feet and the width is 5 feet
