A rectangular garden has width 7 meters less than the length

A rectangular garden has width 7 meters less than the length? The area of rectangular garden is 78 square meters. Find the width of a garden. 6 ft 5 ft 13 ft 4 ft

Solution

Let the lenght is (x) mtr

bredth = (x-7)mtr

Area of rectangle = L*B

puttting all the values

L*B = 78

x(x-7) = 0

x^(2) - 7x - 78 = 0

x = 13mtr which is lenght

so bredth = 5 mtr
