Question

Perimeter = ?
Length = 2x
Breadth = x

Answer 1

Answer:

Perimeter of Rectangle = 2×(L+B)

Given that:

L= 2x, B= x

By putting the L and B in above formula as:

=》2×(2x × x)

=》2×( 2x^2)

=》4x^2

Hence 4x square is the required answer!

WE KNOW THAT

perimeter= 2(l+b)

perimeter=2(2x+x)

perimeter=6X

For more information

Perimeter of Rectangle = 2(l+b)

Area of Rectangle= length× breadth

Area of Rohmbus= (d1×d2)/2

Area of Trapezium= 1/2(sum of parallel sides)×h
