Please help I've been waiting for the past 30 min...

Thomas built a sand castle that measured 134 centimeters
by 127 centimeters, and dug a moat around it.
Afterward, he decided to change the castle size, making it
104 centimeters by 201 centimeters.
How much longer will the new moat be than the old one?​

Answer 1

67 cm

Explanation:

length is the longest side of the rectangle and width is the shorter side

First rec L=134, W=127

Second rec: L=201, W=104

so 201-134 = 67

Answer 2

Answer:4 meters longer.

Explanation:

Amit built a sandcastle that measured 600 cm by 600 cm i.e. 6 meters by 6 meters.

Therefore, its perimeter is 2(6 + 6) = 24 meters

Now, afterward, he decided to change the castle size, making it 8 meters by 6 meters.

Therefore, its perimeter is 2(6 + 8) = 28 meters

Therefore, the perimeter of the new castle is increased by (28 - 24) = 4 meters.

If Amit dug a moat around his castle then the new moat will be 4 meters longer than the old one. (Answer)

As the moat is dug around the castle, its length will be the same as the perimeter of the castle.
