85 cm^2

Step-by-step explanation:

split the given figure and form square and rectangle

find area of rectangle

length = 15 cm

breadth = 4 cm

area of rectangle = l*b

=15*4

=60 cm^2

area of square = l^2

=5^2

=25 cm^2

area of figure = area of rectangle + area of square

=60 cm^2 + 25 cm^2

=85 cm^2

85

Step-by-step explanation: Start at the top, 5 x 5 = 25, right under it would be 4 x 5 = 20, now you have 10 x 4 = 40, 25 + 20 + 40 = 85

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
