31.41

Step-by-step explanation:

62.38

Step-by-step explanation:

1. decimal with 2 decimal places (.XX)

2. less than 100 (XX.XX)

from here, let's assign variables to our number: AB.CD

C = 1,3,5

A = 3B

D = A + B (must be less than 9)

A = 2C

with these limitations, we can extrapolate that A must be divisible by both 2 and 3. what number less than 9 has these factors? 6

A = 6

this means that B = 2 and C = 3

and, now with A and B, D = 8

so, putting them all together: AB.CD = 62.38

21 i watched a 3 hr vid explaining it

step-by-step explanation:

du what else would it be

brainliest

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

happy to

pls mark as brainliest
