question 2 answer will be = the area is 2025 square cm

Answer 2

$\huge\underline\mathfrak{1.\:SolutiOn-}$

perimeter of a triangular garden sides = 65 m, 70 m and 80 m.

The total amount = Addition of all the sides

                             = 65 + 70 + 80

                             = 215

cost of fencing the garden = ₹ 550

                                             = 215 × 550

                                             = 118250

$\large{\sf{\purple{:.The\:total\:amount\:is\:118250}}}$

$\huge\underline\mathfrak{1.\:SolutiOn-}$

Each side of a square piece of cardboard = 45 cm

The area of  the cardboard = 45 × 45 × 45 × 45

                                             = 4100625

$\large{\sf{\purple{The\:area\:of\:the\:cardboard\:is\:4100625}}}$
