Question

what are the 2 missing dimensions on the outside of the area model?what are the 2 missing dimensions on the inside of the model?write the area as a product equivalent to the area as a sum

Answer 1

The figure given shows a rectangular shape divided into four parts labelled partially. The area of HJFG is shown as x². One of its sides is labelled as x. The area of shape is

Area = L * W

x² = x * W

Therefore

x² / x = W

x = W

This is because the length or width of one side is derived by dividing the area by the other side which has been given, hence side HG is x.

Also line AH = line CD and that is 5. If line CD is 5, and the area of BCDJ is 1
