What is the area of this parallelogram?

340 square cm (Answer choice B).

Step-by-step explanation:

Even tho' the ends are slanting (they are not vertical), the formula for the area of such a parallelogram is A = (height)(length).  In this case, A = (17 cm)(20 cm), or 340 cm^2.

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.
