Question

how many rectangle can be drawn as 18cm as perimetere

Answer 1

Given:

Perimeter of rectangle, P = 18 cm

Find:

The number of rectangles.

Answer:

Four (4) rectangles can be formed.

Solution:

Perimeter of rectangle = 2(l + b)

where l = Length of the rectangle

b = Breadth of the rectangle

P = 2(l + b)

18 = 2(l + b)

2(l + b) = 18

l + b = 18/2 = 9

Length + breadth = 9

If l = 8 cm and b = 1 cm, then rectangle can be formed of perimeter 18 cm.

If l = 7 cm and b = 2 cm, then rectangle can be formed of perimeter 18 cm.

If l = 6 cm and b = 3 cm, then rectangle can be formed of perimeter 18 cm.

If l = 5 cm and b = 4 cm, then rectangle can be formed of perimeter 18 cm.

Hence, four rectangles can be formed.

Answer 2

Answer:

four rectangles can be formed

Step-by-step explanation:

perimeter-2(l+b)

18-2(l+b)

l+b -- 18/2-9

using 9 4 rectangles can be formed
