Question

6. Find the area of a rectangle whose breadth is 7 m and its perimeter is equal to that of a square with side 12m​

Answer 1

Answer:

side = 12 m

Perimeter = 4a

           = 4*12

             = 48 m

therefore , 2 ( l+b ) = 48

             l+7 = 48/2

      length = 24 -7

                  = 17

Area = lb

        = 17*7

        =  119 m units

Answer 2

Step-by-step explanation:

we know that the perimeter of a square is

=4*side

=4*12=48

perimeter of a rectangle =2(l+b)

=2(l+7)=48

=(l+7)=48/2

= l=24-7

= l=17m

Area of rectangle = 7*17

=119msquare
