Answer 1

Hi...☺

Here is your answer...✌
==============================

Given that,
Side of square tile , a = 25cm

Area of each tile = a²

= (25cm)²

= 625 cm²

Now,
Area of hall = no. of tiles × Area of each tile

= 500×625 cm²

= (500×625)/1000 m²
{Since 1cm² = 1/1000 m²}

= 31.25 m²

Hence, Area of hall is 31.25 m²

Answer 2

Answer :-

Length of square tiles = 25 cm

Number of tiles = 500

Area of hall = 500 × 0.25 m

= 31.25 square meter
