Idon't know what to do
-find 3/8 of 40.

Well, because 40 is divisible by 8, just divide 40 by 8, which is five, and multiply the five by the numerator - 3.

40 / 8 = 5

5 * 3 = 15

15 = 3/8 of 40 

I hope this helped you!

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
