Answer 1

Answer: The mistake caused the perimeter to increase by 4 inches

The mistake caused the area to increase by 13 square inches

Step-by-step explanation: The original dimensions have been given as 5 inches by 7 inches. If this measurement had been correctly used, the perimeter was supposed to be;

Perimeter = 2(L + W)

Perimeter = 2(5 + 7)

Perimeter = 2(12)

Perimeter = 24 inches

Also the area was supposed to be;

Area = L x W

Area = 5 x 7

Area = 35 square inches

However, Sam accidentally printed a photo that is 6 inches by 8 inches, therefore the effect would be as follows;

Perimeter = 2(L + W)

Perimeter = 2(6 + 8)

Perimeter = 2(14)

Perimeter = 28 inches

And the Area would be

Area = L x W

Area = 6 x 8

Area = 48 square inches

From the calculations so far, the mistake would cause the perimeter to increase by 4 inches (28 inches - 24 inches).

Also the area would likewise increase by 13 inches (48 inches - 35 inches).
