Darcy uses place-value blocks to show a number. she use 4 thousand blocks and 5 hundred blocks .whats is the number? how can she uses place-value blocks to show the number? explain?

The number is 4,500.00

From the decimal point, moving to the left, the place values would be ONES, TENS, HUNDREDS, THOUSANDS, TENS THOUSAND, HUNDREDS THOUSANDS.

Since Darcy placed 4 in the thousands blocks, it should look like this 4,000.

Then 5 should be in the hundred block; thus, 500.

Adding both numbers resulted to 4,500. Four thousand five hundred only.

Okay so it will be 1123

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
