4.5 is the range

Step-by-step explanation:

Ok, so it's asking for range, Range means The Highest number minus the smallest number.

What is the highest number? it's "2.3"

What is the lowest number? it's "-2.2"

so subtract those numbers and you get your answer!

Wait... why is the range 4.5? well, you do 2.3-(-2.2) when there are 2 minuses, you switch it to a + sign. so, 2.3+2.2=4.5!

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
