Answer:

HIII

  answer = 4cm

Step-by-step explanation:

length = ? let length be " l "

breadth = 6cm

perimeter = 20cm

formulae of perimeter = 2 ( l + b )

SOLUTION

2( l + b ) = 20

 2l + 2b = 20

2l+ 2×6 = 20

 2l + 12 = 20

        2l = 20 - 12

        2l = 8

          l = \frac{8}{2}

          l = 4

Therefore , LENGTH = 4CM

Given - Perimeter of rectangle = 20 centimetres

Breadth of rectangle = 6 centimetres

Find - Length of triangle from perimeter and breath of rectangle.

Solution - Perimeter of rectangle is calculated by the formula = 2 (l + b), where l denotes length and b denotes breadth.

Keeping the values in formula-

20 = 2 (l + 6)

Solving the formed equation, we get -

10 = l + 6

l = 10 - 6

l = 4 centimetres

Therefore, length of rectangle is 4 centimetres.
