A rectangular yard is 20 yards wide and 40 yards long. It is surrounded by a thick hedge that grows on the border of the propert

borishaifa [10]

Answer:

$W_{h}= 4.275yd$

Step-by-step explanation:

Data

wide=20yd

length=40yd

Hedge area $A_{h}$ = $171yd^{2}$

If the area of rectangle is A=base * hight and our case L*W. then:

$A_{h}=171yd^{2}=40yd*W_{h}$

So $W_{h}=\frac{A_{h} }{L} =171yd^{2}/40yd=4.275yd$
