The larger square garden at volterra hall has sides twice as long as the smaller square garden. together the gardens cover 18,000 square feet. find the dimensions of each garden.

We will call:
: The larger square garden.
: The smaller square garden.

Given that both of then have square areas, then:



Being the side of the larger garden and the side of the smaller garden as shown in the figure.

The larger square garden at Volterra Hall has sides twice as long as the smaller square garden, thus:



Together the gardens cover 18,000 square feet, so:


Then:








Therefore:
Each side of the larger square garden is and each side of the smaller one is each. These are the dimensions.

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
