<span>Perimeter of rectangle=2(l+b) 2(l+b)=74 (l+b)=37 l=37-b Area of rectangle=l*b 330=l*b 330=(37-b)b 330=37b-b^2 b^2-37b+300=0 By solving we get b=12cm and b=25 is neglected as b<l l=25cm and b=12cm</span>

Estimate the sum by rounding each number to the given place value.

romanna [79]

Answer:

400,000

Step-by-step explanation:

The given sum is 164,215+216,088

We simplify this to get:

164,215+216,088=380,303

The digit at the hundred thousand position is the rightmost 3.

The digit after it is 8.

Since 8≥5 we round up.

We add 1 to 3 to get 4 and replace all digits to the right with zeros.

We round to the nearest hundred thousand to get:

400,000
