the school is planning to add 2 new playgrounds each playground will be the shape of a square that measures 21 m by 21 m what will be the area of the playgrounds

The area of the playgrounds will be 441 sq. M.

Step-by-step explanation: This is because to get the area of a square you multiply base time height or b x h = x. So for this all you need to do is solve 21 x 21, which is 441 sq. M.

(P.s if you need the combined area then the answer is 882 square meters.)

Hope this helps.

441 m2 for each so just times that by two

step-by-step explanation:

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
