Answer:
Step-by-step explanation:
The tough part of this question is figuring out what to do with √(7^2). You could do it by expanding the square. √(7^2) = √49
Now what is the square root of 49? Is it not 7?
√49 = 7
7^6 * 7^1
7 ^(6 + 1)
7 ^ 7
Multiply 18 * 3 and 20 * 3
18*3 = 54
20 * 3 = 60
Length = 54 cm ; Width = 60 cm
Area = L x W
54 * 60 = 3240
Area = 3240 cm
