A rectangular board is 1.6 meters long and 1.2 meters wide. What is the area of the board in square millimeters? Do not round yo
Arisa [49]
<h2>Area of rectangular board is 1920000 square millimeters</h2>

Step-by-step explanation:

A rectangular board is 1.6 meters long and 1.2 meters wide.

Here we need to find the area of the board in square millimeters.

Length = 1.6 m= 1.6 x 1000 = 1600 mm

Width = 1.2 m= 1.2 x 1000 = 1200 mm

Area = Length x Width

Area = 1600 x 1200

Area = 1920000 square millimeters

Area of rectangular board is 1920000 square millimeters

Answer:

The largest African elephant weighed 13.5 tons (27,000 pounds) The world record holder weighed this much and stood 13ft/4m tall at the shoulder. There are other species of elephants, namely the Asian and the Indian, but they are much smaller than the African. The African elephant is the king among the giants on land. No other land animal comes close to the size of these creatures. It would take 165 full-grown men to make up the same weight as the world's record African elephant. The noise of an elephant digesting its food (when its tummy's growling) can be heard up to 600ft/183m away. Elephants actually have control over their digestive processes because they are able to stop the sounds of digestion when they sense danger. Here are some other cool elephant factoids:
