Question

A rectangular turf of size 20 feet by 34 feet is surrounded by a flower bed of uniform width

Answer 1

Answer:

9.18 feet

Step-by-step explanation:

dimensions of whole area = (20 + x)(34 + x)

= 680 + 54x + x^2

where x is the width of the flower bed.

we know that x^2 + 54x + 680 = 1200

x^2 + 54x - 520 = 0

x = 9.18 or x = -63.18

width of flower bed cannot be negative therefore it is width 9.18 feet
