First, round 6821 which is 6800 because the number next to the hundreds place (2) is less than five so you add zeros, 6800. Now, round 4963 which is 5000 because the number next to 9 is 6, which is greater than 5 so the nine turns to ten, it adds it to the thousands place, 5000. Lastly, add 6800 and 5000 equals 11800.

I explained so much and I hope you understood.

Marissa would round 6,821 to 7,000 and 4,963 to 5,000. Then she would add 7,000 and 5,000 and get 12,000.
The exact answer would be 11,784.

Answer:

20 inches

Step-by-step explanation:

Since the cape is trapezoid shaped and has an area of 600 in², the area of a trapezoid is given by

A =1/2(a + b)h where a = length along the top of the cape = 24 in, b =  length along the bottom of the cape = 36 in and h = height of the cape

So, h = 2A/(a + b)

= 2 × 600 in²/(24 in + 36 in)

= 1200 in²/60 in

= 20 in

So, the height of the cape is 20 inches
