Question

pls find the perimeter of the rectangle and explain how you got it

Answer 1

Length of the rectangle = 7

Breadth of the rectangle = x-3

Perimeter of the rectangle=2(l+b)

=2(7+(x-3))

=(2×7)+2(x-3)

=14+(2×x)-(2×3)

=14+2x-6

=14-6+2x

=8+2x

Therefore the perimeter of the rectangle is 8+2x
