We know that a soccer field is in the shape of a rectangle; and we know that the area is equal to length times width (A = l*w).
We are given the area as 7,700 sq. yds. and the width as 70 yds., so we can plug those into the equation to find the length (l):
A = l*w
7,700 = l*(70)
l = 100 yds.
With the length known, we can then determine the perimeter, which, for a rectangle, is:
P = 2l + 2w
So we can then plug in the values for the length and the width:
P = 2(110) + 2(70)
P = 220 + 140
P = 360 yds
The perimeter of the soccer field, which we now know, is 360 yds.
Answer:
= -5√7 -(√2)
Step-by-step explanation:
3√7- √7 -2√7+√8 -5√7-3√2
=3√7- √7 -2√7 -5√7+√8 -3√2 (first we place similar radicands together)
=-5√7+√8 -3√2 ( solve the similar radicands)
=-5√7+√2³ -3 (2^1/2) ( break 8 into powers of 2)
=-5√7+ (2)^3/2 -3 (2^1/2) (solve 2 power with the radical sign)
= -5√7+(2^1/2){ 2-3} ( taking2^1/2 as common)
= -5√7+(2^1/2){ -1} ( solving the co - efficients of 2^1/2)
= -5√7 -1 (2^1/2)
= -5√7 -(√2) {answer}
