Answer:

The area of rectangle B is 72 square units

Step-by-step explanation:

Here we have that

Rectangle B = 150% of Rectangle A

If the area of rectangle A is 32 square units, therefore, the area of rectangle B will be

Area of rectangle B = L₁×1.5  ×W₁×1.5 = 2.25×L₁×W₁

Where L₁ and W₁ are the length and width of rectangle A and therefore L₁×W₁ is the area of rectangle A

Which gives the area of rectangle B as

Area of rectangle B = 2.25 × (Area of rectangle A)

∴ Area of rectangle B = 2.25 × 32 = 72 square units.

Answer:

The answer is 72 square units

Step-by-step explanation:

If rectangle A is scaled by 150% that means the length and breadth of rectangle A were both increased by 1.5(150%) to yield rectangle B.

So, the area of rectangle B is 1.5L x 1.5B = 2.25LB

But, LB = area of rectangle A which is = 32

So, area of rectangle B

= 2.25 x 32

= 72square units.

On a certain hot summer day, 481 people used the public swimming pool. The daily prices are 1.25 for children and 2.25 for adult
spayn [35]

Answer:the number of children that swam in the public pool that day is 222

the number of adult that swam in the public pool that day is 259

Step-by-step explanation:

Let x represent the number of children that swam in the public pool that day.

Let y represent the number of adult that swam in the public pool that day.

On a certain hot summer day, 481 people used the public swimming pool. This means that

x + y = 481

The daily prices are 1.25 for children and 2.25 for adults. The receipts for admission totaled to 86.25. This means that

1.25x + 2.25y = 860.25 - - - - - - - -1

Substituting x = 481 - y into equation 1, it becomes

1.25(481 - y) + 2.25y = 860.25

601.25 - 1.25y + 2.25y = 860.25

- 1.25y + 2.25y = 860.25 - 601.25

y = 259

Substituting y = 259 into x = 481 - y, it becomes

x = 481 - 259

x = 222
