The answer is b. It cannot be c cause the answer would be a negative number. It cannot be a because there would be more than 100 lollipops altogether. And it cannot be d because the answer would be a fraction. There was 29 lollipops altogether. Hope this helps!

Jim's backyard is a rectangle that is 15 5/6 yards long and 10 2/5 yards wide. Jim buys sod in pieces that are 1 1/3 yards long

Oduvanchick [21]

Answer:

93 pieces

Step-by-step explanation:

To cover his backyard with sod, he needs to cover the area of the backyard.

His backyard is a rectangle, and area of a rectangle is given as:

$A=lw$

Where,

$l$ is the length, and

$w$ is the width

So, the area of Jim's backyard is $l*w=15\frac{5}{6}*10\frac{2}{5}=\frac{95}{6}*\frac{52}{5}=\frac{494}{3}$ square yards.

The area of each sods are solved using the area of the rectangle formula. So we have $l*w=1\frac{1}{3}*1\frac{1}{3}=\frac{4}{3}*\frac{4}{3}=\frac{16}{9}$ square yards as the area of each sod.
