Question

Q.6 The perimeter of a square is 48cm. the area of a rectangle
is 4cm less then the area of the square if length of the rectangle
is 14cm find its perimeter.​

Answer 1

Step-by-step explanation:

The perimeter of a square is 48 cm

Let side of square be s

4s=484s=48

s=12\ cms=12 cm

Let breadth of rectangle be b

Length, l = 14 cm

Area of rectangle, A_R=14bA

R

=14b

Area of square, A_S=12^2=144A

S

=12

2

=144

The area of rectangle is 4 cm² less than the area of the square.

A_R+4=A_SA

R

+4=A

S

14b+4=14414b+4=144

14b=14014b=140

b=10\ cmb=10 cm

Perimeter of rectangle = 2(l+b)

= 2(14+10)

= 48 cm

Answer 2

Answer:

Area of the square is 58 cm
