Verbs are action that can be mental or physical. Adjectives are words that describe something in detail.
“About Mars” is the Adjective Phrase.
Adjective phrase describes “what kind of which ones”
So for example here
“After school, I looked for books about Mars.”
“About Mars” describes the kind of books so that makes it an Adjective phrase.

First you need to find the area of the garden. The formula for that is A=bh.
the base is 15 and the height is 30. 15 x 30 = 450, making the area of the garden 450 feet.
Next you need to divide the area, 450 by the number of hours it took to install all the grass, which is 4. 450 divided by 4 is 112.5
Emily installed the grass at an average speed of 112.5 feet per hour.
