Answer 1

Answer:

Answer is 4p

Step-by-step explanation:

perimeter=2(l+b)

=2{(p+q)+(p-q)}

=2{p+q+p-q}

=2{2p}

=4p

Answer 2

Given :-

l = p + q

b = p - q

To Find :-

Perimeter

Solution :-

Perimeter of rectangle = 2(l + b)

Perimeter = 2(p + q + p - q)

Cancel ''q'' from both sides

Perimeter = 2(p + p)

Perimeter = 2(2p)

Perimeter = 4p
