Answer 1

Answer:

Step-by-step explanation:

1. Area of square = a^2

a=side of square

area of this square = 10.5 x 10.5 = 110.25 m

2.   perimeter = sum of sides = 3.5 + 3.5 + 3.5 = 10.5 cm

Answer 2

Answer:

iv) The area of the square is 110.25 cm

v)The perimeter is 10.5 cm

Step-by-step explanation:

iv) Formula of the area of square =  A= Side * Side

   Length of one side = 10.5

   Area of the square = A =  10.5 * 10.5 = 110.25

Hence the area of the square is 110.25 cm

v) Formula of the perimeter of an equilateral triangle = 3 * Side

 Length of the side of the equilateral triangle = 3.5

 Perimeter of the triangle = 3 * 3.5 = 10.5

Hence the perimeter of the triangle is 10.5 cm
