Answer:
40 square yards
Step-by-step explanation:
The backyard is rectangular and it's dimensions are 7 yards long and 8 yards wide.
The area of a rectangle is given as:
A = L * W
where L = length
W = width
Therefore, the area of the backyard is:
A = 7 * 8 = 56 square yards
Elliana wants to plant sunflowers on 16 square yards of the backyard and the rest of the backyard will be used for a pool.
The area left for the pool will therefore be:
56 - 16 = 40 square yards
40 square yards will be left for the pool.
