Answer:
area of triangle = 4.5*6/2 = 13.5 sq.yd.
Step-by-step explanation:
The area of a right triangle is half of the product of the sides adjacent to the right angle.
Here the sides adjacent to the right angle are 6 yd and 4.5 yd.
Therefore the
area of triangle = 4.5*6/2 = 13.5 sq.yd.
Dryer cost represented by x
Then, the washer costs (x + $72)
Together, they cost (x) + (x+72) = $772
2x+72 = 772
[subtract 97 from both sides]
x = 350
[divide both sides by 2]
The dryer cost $350
The washer cost $422.
Together, they cost $772
