Question

Some wire is used to make 3 rectangles: A, B, and C. Rectangle B's dimensions are 3 5 cm larger than Rectangle A's dimensions, and Rectangle C's dimensions are 3 5 cm larger than Rectangle B's dimensions. Rectangle A is 2 cm by 3 1 5 cm

Answer 1

Answer: there is 1 3/5 cm of wire left.

Answer 2

Some wire is used to make 3 rectangles: A, B, and C. Rectangle 's dimensions are 3 cm larger than Rectangle A's dimensions, and Rectangle C's dimensions are cm larger than Rectangle B's dimensions. Rectangle A is 2 cm by 3 cm. a. What is the total area of all three rectangles?

The answer is 30.36cm²

Explanation:

Rectangle A dimensions

`L = 3(1)/(5) cm`
`= (16)/(5)`

B = 2cm

Rectangle B dimensions

Length Breath

`L + (3)/(5)`
`B + (3)/(5)`

`(16)/(5) +(3)/(5)`
`2+(3)/(5)`

`(19)/(5)cm`
`(13)/(5) cm`

Rectangle C dimensions

`(19)/(5) +(3)/(5)`
`(13)/(5) +(3)/(5)`

`(22)/(5)`
`(16)/(5)`

Area of rectangle A

16 / 5 × 2 = 32/5 cm²

Area of rectangle B

`= (19)/(5) * (13)/(5) \\\\=(247)/(25) cm^2`

Area of rectangle C

`(22)/(5) * (16)/(5) \\\\= (352)/(25)`

Total area =

`(32)/(5) + (247)/(25) + (352)/(25) \\\\= 30.36cm^2`
