Triangle has base equal to one side of the square and height is also equal to one side of the square.

Since triangle area = ½ x base x height,

Area of shaded triangle
= ½ x length of square x length of square
= ½ x area of square


So ½ x area of square = 50cm²

Area of square = 50cm² x 2 = 100cm²

Now 100cm² = 10cm x 10cm

This means the square has length of 10cm

(I.e area of square = 10 cm x 10cm)



Since all 4 sides of a square have the same length,

Perimeter = 4 x 10cm = 40cm
