If it's a perfect square, that means all four sides are equal in length, meaning the dimensions of length and width are the same.
Area=base*height
The only identical numbers that work to get 100 square feet is 10*10
So, all four lengths around the square are 10 feet, so that's 10 feet*4 sides.
You'd need 40 feet of fencing.
<u>Answer:</u>
Jet average speed was 45.5 miles per hour.
<u>Solution:
</u>
Given that a jet left airport and flew south. A passenger plane left one hour later flying at 52 miles per hour trying to catch up the jet.
After seven hours passenger plane caught up jet.
So distance travelled by passenger plane in 7 hours is same as distance travelled by jet in 7 + 1 = 8 hours as jet plane left 1 hour early.
<em>Distance travelled by passenger plane</em> = speed x time = 52 x 7 = 364 miles
So same distance that is 364 miles is travelled by jet plane in 8 hours.
=> Speed of jet = = 45.5 miles per hour.
Hence jet average speed was 45.5 miles per hour.

Step-by-step explanation:
Hope this helps. Pls give brainliest.
16, think of 4 plus 4 plus 4 plus 4.
