Question

The perimeter of a square is 48 cm. The area
of a rectangle is 4 cm less than the area of the
square. If length of the rectangle is 14 cm, then
its perimeter is​

Answer 1

Answer:

Step-by-step explanation:

Perimeter of square= 4× side

48=4×side

48÷4=side

12=side

Area of square=side×side

=12×12

=144cm^2

Area of rectangle=4cm lesser than that of square

=144-4

=140cm^2

Area of rectangle=l×b

Length=14 cm

Breadth=y

140=14×y

140÷14 =y

10=y

Perimeter of rectangle=2(l+b)

=2(14+10)

=2×24

=48cm
