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

a rectangular garden is 47 ft longer than it is wide. its perimeter is 314 ft. what is the equation to describe the width and le

Ronch [10]

The perimeter = 2 length + 2 width

the length = the width +47

314 = 2*(w+47) +2w

314 = 2w +94 +2w

220 =4w

w= 220/4 = 55

l = 55+47 = 102

the length = 102 ft

the width = 55 ft
