Answer:

$58.91m^2$

Step-by-step explanation:

(smaller triangle below)

$A=\frac{ab}{2}\\ =\frac{8.6*5.5}{2}\\ =23.65m^2\\\\A=\frac{ab}{2}\\ =\frac{8.6*8.2}{2} \\=35.26m^2$

(bigger triangle above)

Since you have both triangle, and all lengths you dont need to worry about calculating the square

Add both together

$23.65+35.26\\=58.91m^2$

Answer: Loss of 3 yards

Step-by-step explanation:

The overall gain or loss of all 5 plays will be gotten by adding all the results of the plays given and this will be:

= 7 + 2 - 5 - 23 + 16

Collect like terms

= 7+2+16-5-23

= -3

The overall loss of all 5 plays will be -3 yards or loss of 3 yards
