Answer:
width = 4.72m
length = 12.72m
Step-by-step explanation:
width = x
length = x+8
Area = length × width
60m² = (x+8)(x)
60m² = x²+8x
x²+8x = 60
x²+8x+16 = 60+16 [COMPLETING THE SQUARE]
(x+4)² = 76
√(x+4)² = √76
x+4 = √76
x = -4+√76
x = about 4.72
width = 4.72m
length = x+8,
length = 4.72+8
length = 12.62m
For exact measurements:
width = -4+√76 meters
length = 4+√76 meters
