Suggest 2 possible dimensions of the rectangle.

e.g.

Length of rectangle = 2x + 2y cm

Breadth of rectangle = x + 0.5y cm

Check:

Perimeter = 2 (2x + 2y) + 2 (x + 0.5y) cm

= 4x + 4y + 2x + y cm

= 6x + 5y cm

Enter your suggested dimensions in Comments.

Indicate any assumptions made.

Length: 2.5x + 1.5y

ReplyDeleteBreath: 0.5x + 1y

Check: 2(2.5x + 1.5y) + 2(0.5x + 1y)

=6x + 5y cm

____________________________________________

Length: 2.75x + 2y cm

Breath: 0.5x + 0.5y cm

Check: (2(2.75x + 2y) + 2(0.5x + 0.5y))

=6x + 5y cm

Length: 3x

ReplyDeleteBreadth: 2.5y

2nd)

DeleteLength: 2.5y

Length: 2.5y

Breath: 3x

Perimeter: 2(2.5y)+2(3x)=(6x+5y)cm

Length:(-2x+5x)cm

ReplyDeleteBreadth:(-4y+5y+1.5y)cm

Perimeter:2(-2x+5x)+(-4y+5y+1.5y)=(6x+5y)cm

1) Length: (2x+1.5y)cm

ReplyDeleteBreadth: (x+1y)cm

Check: (4x +3y)cm + ( 2x+2y)cm = (6x+5y) cm

2) Length: ( 1.5x+2y)cm

Breadth: (1.5x+0.5y)cm

Check: (3x+4y) + (3x+1y) cm = 6x+5y

1)Length:2x-0.5y

ReplyDeleteBreadth:x+3y

Check:(2x+x+3y-0.5y)X2=(3x+2.5y)X2

=6x+5y

2)Length:4x-y

Breadth:3.5y-x

Check:(4x-x)+(3.5y-y)=3x+2.5y

(3x+2.5)yX2=6x+5y

Length:3x-1

ReplyDeleteBreadth:2.5y+1

Check:(3x-1)+(2.5y+1)+(3x-1)+(2..5y+1)=(6x)-2+(5y)+2=6x+5y

Length: (2x + 2.5y)cm

ReplyDeleteBreath: x cm

Check:

Perimeter=(2x + 2.5y) cm x2 + x cm x2=(6x + 5y)cm

length+breadth= (2x+2.5y)cm

ReplyDeleteHow do you find the perimeter of a rectangle?

DeleteWhat's the formula?

Length: (3X + 1.5Y)cm

ReplyDeleteBreadth: Ycm

Check: [(3X + 1.5Y)cm x 2] + Ycm x 2 = (6X + 3Y)cm + 2Ycm

= (6X + 5Y)cm
