4. The edge and corresponding height of a triangular glass placed over a table
20 cm and 8 cm respectively. The area of the triangular glass is 12cm​

Answer 1

Answer:

3=area of rectangle = l*b an area of square=side*side

L*B =SIDE*SIDE

=L*3=9*9

=3L=81

=L=81/3=27

L=27

PERIMETER OF RECTANGLE=2(L+B)

=2(3+27)=60

perimeter of rectangle is 60
